When using repo as library, incorrect version of burn gets used, adding version tag to cargo.toml may fix

[SamuelKurtzer]

Been having trouble using this in a project and I think I've discovered why, when imported as a library burn v0.13.0 is pulled whereas in its own repo whisper uses 0.9.0.

Adding a tag to the cargo.toml may fix this issue, hopefully I can make a branch off this issue to test.
