Complete bindings #29
Description
Ideally we'd cover everything in the C library.
Some of the more important stuff we're currently lacking involves querying device capabilities e.g. driver_version, repeat, the remaining parts of abs_info.
In some cases, we'll need to think carefully about what a pleasant high-level API could look like. Indeed, in some cases, a 1-1 mapping mightn't really make sense (e.g. #10).
