621d7f2c22 decode: Align some heavily used structs to save space
From betteralign:
Compound: 8 bytes saved: struct with 40 pointer bytes could be 32
Value: 40 bytes saved: struct with 128 pointer bytes could be 88

ac276ee119 gzip: Correctly handle multiple members
A gzip file consists of one or more "members" that are concatenated on uncompress.

Introduce a members array with each member and uncompressed is now the concatenation.

Fixes #794

e2eb667091 html: Add to probe group
As decoder now can know they are decoding as part of probing we can now
use some heuristics to see if we should decode as html.
The reason heuristics is needed is that x/html parser will alwaus succeed.

Add lazyre package to help delay compile of RE and make it concurrency safe.

b08ef00dd1 decode,interp: Refactor format groups into a proper struct
Replaces []Format with a Group type.
A bit more type safe.
Breaking change for RegisterFormat, now takes a first argument that is a "single" format group.
Lots of naming cleanup.

This is also preparation for decode group argument which will enable doing intresting
probing, ex a format decoder could know it's decode as part of probe group  (html could
be probed possibly), or have "arg probe" group for decoder who inspect args to know
if they should probe (-d /path/to/schema etc) to enable nice CLI-ergonomics.

c5f6809b02 decode,fuzz,dev: Move recoverable error check to recoverfn.Run
This preserves the callstack on non-recoverable panics so that using
a debugger and fuzzing is much easier.

Add vscode debug config.
Remove fuzz stacktrace log workaround.

9852f56b74 tls: Add TLS 1.0, 1.1, 1.2 decode and decryption
What it can do:
- Decodes records and most standard messages and extensions.
- Decryptes records and reassemples application data stream if a keylog is provided
  and the cipher suite is supported.
- Supports most recommended and used ciphers and a bunch of older ones.

What it can't do:
- SSL v3 maybe supported, is similar to TLS 1.0, not tested.
- Decryption and renegotiation/cipher change.
- Record defragmentation not supported, seems rare over TCP.
- TLS 1.3
- SSL v2 but v2 compat header is supported.
- Some key exchange messages not decoded yet

Decryption code is heavly based on golang crypto/tls and zmap/zcrypto.

Will be base for decoding http2 and other TLS based on protocols.

Fixes #587

8e0dde03d0 decode: Support multiple format args and some rename and refactor
This will allow passing both cli options and format options to sub decoder.
Ex: pass keylog option to a tls decoder when decoding a pcap.
Ex: pass decode options to a format inside a http body inside a pcap.

Add ArgAs method to lookup argument based on type. This also makes the format
decode function have same signature as sub decoders in the decode API.

This change decode.Format a bit:
DecodeFn is now just func(d *D) any
DecodeInArg renamed to DefaultInArg

9b81d4d3ab decode: More type safe API and split scalar into multiple types
Preparation to make decoder use less memory and API more type safe.
Now each scalar type has it's own struct type so it can store different
things and enables to have a scalar interface.
Also own types will enable experimenting with decode DLS designs like
using chained methods that are type aware.

c93301fc70 raw,bits,bytes: Replace raw format with bits and bytes format that decode to a binary
raw format was a hack to skip decoding to be able to get a binary using tobyte etc.
Now you can do fq -d bytes ... instead of fq -d raw 'tobytes | ...'

768df3012c interp,decode: For struct use map to lookup field
Will make it faster for struct with logs of fields and seems to
not cuase any significant difference for small structs.

All this really needs a rewrite somehow, maybe refactor into interfaces somehow? getting messy.
