Document --prefix and --script-root as cli options that are available to use from func start

Background

We are currently working on a TypeScript project where our code is laid out as following:

src/
  FunctionOne/
  - function.json
  - index.ts
  FunctionTwo/ 
   - function.json
   - index.ts
 - host.json
 - shared/*
 - ...

And the corresponding output from the tsc compiler:

src/
  FunctionOne/
  - function.json
  - index.js
  FunctionTwo/ 
   - function.json
   - index.js
 - host.json
 - shared/*
 - ...

However to get this approach working we had to navigate trough several issues and comments on this topic. And to make our code work locally we had to prefix the func start with --prefix dist or otherwise we could also use --script-root dist, but it seems that using --prefix is the best option. These options have been available for a while but they are not documented and neither available from the CLI options for the func start command.

Proposal

If these options are meant to be used it would be nice to have them documented or at least available from the CLI. I am open for making a contribution / PR, but would like your input on the topic first…

@cristobal Thanks for pointing this out! Yes, if you could add the documentation for both --prefix and --script-root in a PR, that would be fantastic.

Aight will look into it this week, sorry did not see this reply before now. Been a bit busy at work and drown in Github messages at work need to sort out the notifications here somehow 😂
