Various packages lack source mapping support

Issue

I noticed that @truffle/codec (on next) uses source-map-support to allow for source mapping despite being written in TypeScript. It seems likely this should also be used in our other TypeScript packages (or compiled packages more generally, such as the debugger, which is written in JS but compiled with Webpack).

Many @truffle/ packages result in error: Module not found: Error: Can't resolve 'module' in ..node_modules/source-map-support in versions 0.5.16, 0.5.18 source-map-support. I found a fix here:
evanw/node-source-map-support#273

@nogo10 Could you open a new issue for this? What you're reporting is a different issue than what this issue was originally about (this issue should have been closed). Thank you!

OK, @nogo10 I've thrown up PR #3036 to hopefully fix your problem. In the future feel free to do this sort of thing yourself! :)

OK, this should hopefully be fixed now. Closing this. If it's not fixed, could you open a new issue rather than reopening this one? Thank you!
