Fix start time logic for file loading

[ZachNagengast]

Resolves #191

Issue occurs when an audio file requires resampling and startTime is not 0. Previously, the resample function calculated the total frame count and reading up to that number as the frame position (which would imply that the start time was always 0 in the resample function). The solution involves calculating the start and end frame positions by incorporating the starting frame position as an offset and reading up to the end position correctly rather than just the total frame count.

• Correctly calculates starting frame position to read files when startTime is not 0
• Adds new optional parameter to loadAudio protocol maxReadFrameSize for easier memory management with large files
• Adds tests for this logic
• Adds a couple minor QoL improvements for edge cases and logging
