Compiling SZ3 on 32bit systems (wasm32 in my use case) fails because of the ska_hash implementation, which expects that
size_tis 64b wide. While there have been attempts to port ska_hash to 32 bits, e.g. in skarupke/flat_hash_map#18, pulling in those changes would place the maintenance burden on SZ3.In this PR, I'm instead suggesting a simpler solution by falling back to the
std::unordered_mapimplementation on non-64bit systems, whereska::unordered_mapis not available. This immediately unlocks 32bit support with a minimal code change.
