`fluid.bufnmf~` crashes with fft size larger than file length about flucoma-core

[rconstanzo]

This is on version 1.0.6+sha.e748875.core.sha.f694a366 but I have some of the new bits that @tremblap has posted on discourse.

Here's a crash report with the spicy bit being here methinks:

And a simple patch to cause the crash.
