Add WASM build
Some things needed adjusting for 32-bit systems: - Factors of polynomials are sorted into a consistent order - Some arb doctests have slightly different results and are skipped - The field generated by fq_default for a given order can be different. The doctests for gr_nf and gr_nf_fmpz_poly are disabled because they otherwise crash with `RuntimeError: memory access out of bounds.` wich means that there is a bug somewhere.
