pls let me stop finding chrome bugs

two browser-bugs in two hours, man i just wanna play horizon

• read-only demo server at https://a.ocv.me/pub/demo/
• latest gzip edition of the sfx: v1.0.14

bugfixes

• chrome randomly running out of memory while hashing files and mt is enabled
  • the gc suddenly gives up collecting the filereaders
  • fixed by reusing a pool of readers instead
• chrome failing to gc Any Buffers At All while hashing files and mt is enabled on plaintext http
  • this one's funkier, they've repeatedly fixed and broke it like 6 times between chrome 84 and 106
  • looks like it just forgets about everything that's passed into wasm
  • no way around it, just show a popup explaining how to disable multithreaded hashing
