- Added token_reader::read_some(), which takes a view of a token buffer
reads/unpacks up to that many tokens from a buffer. If an error occurs,
or if there are fewer msgpack formats within the buffer, then the
returned span will be a subspan of the original buffer. If no tokens
were read before encountering an error, token_reader will return the
error instead.
- token::operator== overload for types that might be stored within the
token. Handy for cleaning up tests, even though both methods of
`token::get<T>() == value` and `token == value` are represented for
now.
- Added a simple tool to open a file containing msgpack content and read
tokens into a buffer. This is for testing speed, but needs to be made
into a proper benchmark once more work has been done. Pretty fast
right now, only taking 2us to parse ~200 tokens (that takes the
pythong msgpack implementation ~1s to handle).
