Add support for outputting IIDX tape LED data via spiceapi (#315)

## Link to GitHub Issue, if one exists
#41 (partially)

## Description of change
This PR adds support for outputting IIDX tape LED data via spiceapi
(`iidx_tapeled_get()`). It returns the data as a `dict`, with the key
being the LED name and the value being the list of RGB values. You can
optionally pass in a variadic list of names to filter the returned data.

The new API function is only implemented in Python since I'm not able to
test the wrappers in other languages.

An example script using the new API is available in this Beef Board PR:
https://github.com/HWXLR8/beef-board/pull/133.

Demo use case: https://streamable.com/pq5e1e

## Testing
Tested in IIDX 32 with custom Beef Board firmware along with a Python
script to read and send the tape LED data over USB.
