## Message

```
std.cache_hash: break up the API and improve implementation

into smaller exposed components and expose all of them. This makes it
more flexible.

`*const Cache` is now passed in with an open manifest dir handle which
the caller is responsible for managing.

Expose some of the base64 stuff.

Extract the hash helper functions into `HashHelper` and add some more
methods such as addOptional and addListOfFiles.

Add `CacheHash.toOwnedLock` so that you can deinitialize everything
except the open file handle which represents the file system lock on the
build artifacts.

Use ArrayListUnmanaged, saving space per allocated CacheHash.

Avoid 1 memory allocation in hit() with a static buffer.

hit() returns a bool; caller code is responsible for calling final() in
either case. This is a simpler and easier to use API.

writeManifest() is no longer called from deinit() with errors ignored.

```
