Help text generated by `clap` contains the full file name (including
extension) of the binary. On Unix-like systems, binaries commonly do not
have any file extension. On Windows, ".exe" is common.
To allow testing such output, introduce a new marker "[EXE]" that is
substituted accordingly. The idea and syntax is taken from
https://docs.rs/trycmd/1.0.0/trycmd/#toml
Command line parsing differs on Windows vs. POSIX compliant operating
systems (just consider the differences in handling `\` for paths vs. as
a marker for escape sequences). Thus, on Windows use `winsplit` to
split command arguments instead of `shlex` for Unix-like OSes.
`winsplit` is a small crate with no other dependencies.
Introduce the `radicle-core` crate for housing data types that are at
the core of the Radicle protocol. The initial data type being added is
`RepoId`. To make the crate as lightweight as possible many of
dependencies are optional and gated by feature flags.
The crate is marked as `no_std` even though it unconditionally depends
on `radicle-crypto`, which is *not* `no_std`. This is to invite
refactoring of `radicle-crypto` to `no_std` at a later time.
The upgrade of the `radicle-crypto` crate was missed when upgrading
semver versions.
Unfortunately, since it is at the base of the dependency tree, all
crates that depend on it require an additional upgrade.
