This releases adds \0 NUL terminators at the end of .string directives.
It also changes how characters are displayed when looking at memory:

>> memory 1000 6
 INFO address=1000 value=h (0x68)
 INFO address=1001 value=e (0x65)
 INFO address=1002 value=l (0x6c)
 INFO address=1003 value=l (0x6c)
 INFO address=1004 value=o (0x6f)
 INFO address=1005 value=0

>> memory 1000 6
 INFO address=1000 value=Char
 INFO address=1001 value=Char
 INFO address=1002 value=Char
 INFO address=1003 value=Char
 INFO address=1004 value=Char
 INFO address=1005 value=8059

Releases are now fully automated (appart from the release notes) via GitHub Actions, and the whole CI workflow is substantially faster.

This release enhances the CI workflows, which now cross-compiles Windows/macOS/Linux binaries for the aarch64/x86_64 architectures.

It also bumps all dependencies: the most user-visible bump being clap v4.0 (#329).

Now shows error locations on compilation error

Highlights of this release are:

• // C-style comments are now properly supported
• Better validation of instructions when compiling
• More meaningful logs
• Better runtime errors

Main change: words are now i64 (previously u64) and addresses are now u32 (previously u64).
This means programs can now handle negative values.

The CLI now accepts a -v/--verbose option that increases the log verbosity.
It can also generate shell completion scripts for various shells (see z33-cli completion --help).

This is a first release, with binaries available for Linux, macOS and Windows (x86_64)
