chore(profiling): Change continuous profile buffer size

[Zylphrex]

This lowers the sampling frequency of continuous profiles to 21Hz and increases the buffer size to 1 minute to match the desired settings for continuous profiling.

Holding off on merging this until I confirm a few things.

Only bumping the buffer size to 1min and keeping the sampling frequency at 101hz. Reducing the sampling frequency on the SDK will cause pains that are difficult to undo.
