Faster Kaldi on WASM

[msqr1]

I followed the very old instructions to build Kaldi for WASM here: https://gitlab.inria.fr/multispeech/kaldi.web/kaldi-wasm/-/wikis/build_details.md

I found out that the performance with this was very slow probably due to it using the reference BLAS and Clapack 3.2.1

I built Kaldi with OpenBLAS 0.3.28 with some mini hacks and performance increased by 20%. I used the RISCV64_GENERIC target (no architecture-specific optimization, but generally optimized, unlike reference BLAS)

Here are the steps' details (I'm building this for Vosk): https://github.com/msqr1/Vosklet/blob/main/src/make

Would you like me to make a full guide on this to replace the old one and update support for compiling to WASM?

yeah, I think we would be happy to merge this y.
