This imports symbol maps generated by emscripten using the --emit-symbol-map flag. It allows you to visualize a profile captured in a release build as long as you also have the associated symbol map. To do this, first drop the profile into speedscope and then drop the symbol map. After the second drop, the symbols will be remapped to their original names.

Thanks! I fixed this up in #76, which is formatted with prettier & has basic tests
