Issues with Numba 0.55.2

[bendikhk]

We are experiencing errors with Resampy 0.3.0 and Numba 0.55.2. Downgrading to Resampy 0.2.2 fixes the issue. Error log below.

Can you provide an example that triggers this error? My hunch here is that it's not a numba version issue (I'm also on 0.55.2) but something is coming up integer-typed when it needs to be floating point.

@bendikhk just as a heads up, the PR I just merged (#104) might resolve this issue for you. If you have a chance, could you try installing it and give it a whirl? If it does fix it for you, I'll push the 0.3.1 release. If it doesn't, I'd like to get your issue resolved before release.

[bendikhk]

@bmcfee Yep, the fix has resolved our issue. Thank you for the quick response! :)

[bmcfee]

Excellent, thanks for letting me know. I'll push the release then.
