api: allow lights.read() to be filtered by light names (#271)

## Link to GitHub Issue, if one exists
Fixes https://github.com/spice2x/spice2x.github.io/issues/179

## Description of change
Previously, lights.read() did not accept any parameters, instead it
returned all lights implemented by the current game.
Problem is that this is too large for some embedded implementations;
also just inefficient.

Add code to accept light names as strings and only return those in the
result.
For performance, use `robin_hood::unordered_map` to speed up the lookup
operation, which was previously a linear search.
Add this to Python wrapper library. Did not bother with others.

Also, as a bonus - update lights.write_reset() to also accept a flat
list of strings, as opposed to array containing a string, which was
silly.

## Compiling
➕ 

## Testing
Tested using spiceremote and writing a short Python program.
