feat: Voice Message Sending

[Icebluewolf]

Summary

Adds support for sending voice messages. This includes the waveform and duration_sec parameters
Solves #2575

This will be a draft until I have confirmed the behavior of waveforms and duration_sec in interaction responses.
As of now I believe there is a discord bug that causes them to be ignored.
Resolved: Also Pending: DAPI #7158

DAPI #7158 has been closed and I've been using this PR in a project for a couple weeks now without issues. Is it ready to merge?

As far as I know this has not been officially added to the API as it is not strictly documented. Also last time I tested it I was having issues getting the waveforms to display on interaction responses.
