Separate streamly tests into another package

To be able to use an internal test library, we need to have it as a separate package. See comments in streamly-benchmarks.cabal for details. Use a test library for common test modules Also, added "opt" flag to control optimization levels. Add a README for tests. Update benchmarks readme.

+
+## Build and run single benchmarks:
+
+For quick results you may have to use `--quick` and possibly some other
+`gauge` options, or better use `bench.sh --quick` as described in the
+following sections.
+
+```
+$ cabal run bench:Prelude.Serial -- --quick
+```
+
+`cabal bench` can be used but you cannot pass arguments (like --quick):
+
+```
+$ cabal bench Prelude.Serial
+```
+
+## Build and run all benchmarks
+
+Don't try this, it will take too long, use the `bench.sh` method instead.
+
+```
+$ cabal bench all
+```
+
+or:
+
+```
+$ cd benchmark; cabal bench
+```
+
+or this, note this command does not work from "benchmark" dir:
+
+```
+$ cabal bench streamly-benchmarks
+```
+
+## Building and Running Benchmarks with bench.sh

 `bench.sh` script at the root of the repo is the top level driver for running
 benchmarks. It runs the requested benchmarks and then creates a report from the
 results using the `bench-show` package. Try `bench.sh --help` for available
 options to run it.

-## Quick start
+## bench.sh: Quick start

 You must be in the repo root directory to run these commands.

+
+## Naming of test modules
+
+Tests are organized by source modules. For example, for the source
+module `Streamly.Data.Array` and `Streamly.Internal.Data.Array` we have
+a test module `Data.Array`. For some modules tests for a source module
+are broken into multiple modules. For example, for `Streamly.Prelude` we have
+`Streamly.Prelude.Serial`, `Streamly.Prelude.Async` etc.
