v1.1.0: Update vendored blis to 1.0 (address Windows crashes), widen numpy compatibility

The 0.9 version of Blis vendored in this package's v1.0 had memory access errors on Windows.

I've had trouble rolling back to v0.7 to address this, as it isn't building on Github Actions (some environment/compiler toolchain version issue). I've therefore updated the vendored Blis to v1.0, which seems to address the crashes.

I've also widened the numpy compatibility across v1 and v2. I had thought we had to use the same numpy version we built against, but this isn't the case.
