Fix JUMBF and thumbnail errors

[dkozma]

Changes in this pull request

• Fixes error on read that would get triggered if an ingredient doesn't have a thumbnail
• Allows assets that have invalid JUMBF box to have their sources passed through to the client during a read request instead instead of throwing an error so that the asset can still be displayed
• Fixes TypeScript errors by updating our target to es2017 to use some newer (but widely supported) JavaScript APIs, as well as removing process.env in favor of a constant for the integrity logic
• Updates detector and toolkit to add the new --weak-refs flag available in wasm-pack 0.11.0, as well as adding --reference-types to detector (omitted on toolkit since we get a memory access error in Safari)
• Remove dependency on wee_alloc since it is unmaintained and has a reported memory leak
• Updates Rust dependencies and @rollup/plugin-replace
