TypeScript definitions are missing SourceMapConsumer.initialize

[jlfwong]

Hi!

The SourceMapConsumer interface defined in source-map.d.ts is missing a definition for initialize. I think all that's needed is:

initialize({"lib/mappings.wasm": string | ArrayBuffer}): void

Would you accept a PR for this? I'm not sure what the right comment to put above it would be.

Hello... it's been a few months, this is a blocker for me too.

I think a PR for that would be appreciated!

@jkrems I just noticed that source-map.d.ts was indeed missing an entry for that function and submitted the PR above. I'd be glad to make any changes if necessary.
