too late to beat Hyrum's law. It is now considered permissible.

This contains Path and PathBuf, representing platform-independent paths
representable by the castore model.
These are always relative, and platform-independent, which distinguishes
them from the ones provided in the standard library.
A subsequent CL will move IngestionEntry (and more) to use them.

These may as well be inlined, and hardly need tests, since they just
alias AsyncReadExt::read_u64_le / AsyncWriteExt::write_u64_le.
Boolean reading is worth making explicit, since callers may differ on
how they want to handle values other than 0 and 1.
Boolean writing simplifies to `.write_u64_le(x as u64)`, which is also
fine to inline.

Neither of these are necessary if we make the constructor async,

As a bonus, this makes BytesReader::len sensibly typed, and permits
implementing is_empty, as Clippy demands of us.

Also, the non-JSON output is a bit too spammy, as remarked in cl/11483 -

If any of the following happens, then the currently in use reader must
be abandoned:
* A directory or file reader encounters an error
* A directory or file reader is dropped before being fully read from
Additionally, a directory reader must not be read from again after it
has returned None.
These checks are only used when debug_assertions are on, so vanish in
