Allow the user to highlight sections of the edited document, giving them
arbitrary background colors. These annotations can be created from a
selection, or by manually specifying the start and end offsets.
Annotations can be edited or deleted by right-clicking them.
Any color can be used for the background. Dark colors automatically make
the text white for easier readability. When creating a new annotation,
we use whatever color the user last picked as this is slightly more
likely to be the one they want.

That's what this class really is; in fact that's what the first line of
the comment says it is.
This commit does not rename the main files, since those will contain
other time-related classes in a little bit.
Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
This function is made from what composed `set_file()` (which now calls
the new function). It allows to create a `HexDocumentFile` without
calling the hackish `set_file(move(m_file))`.
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.
To support editing of large files it is an advantage to not load the
entire file into memory but only load whatever is needed for display at
the moment. To make it work, file access is abstracted into a socalled
HexDocument, of which there two: a memory based and a file based one.
The former can be used for newly created documents, the latter for file
based editing.
Hex documents now do track changes instead of the HexEditor. HexEditor
only sets new values. This frees HexEditor of some responsibility.
