Add command to export Studio project contents

[isc-bsaviano]

This PR fixes #851

This PR adds a new command that allows the user to export the files (and optionally breakpoints) contained in a Studio project to a workspace folder on their local file system. This is intended to make migrating from Studio to a client-side workflow much easier.

I tested this using a simple project that contained a class, mac routine CSP folder, and a 2 breakpoints:

^oddPROJECT("FIX_851")=$lb("2022-02-11 14:08:07.5016053","","","","",,"","","","","","","","")
^oddPROJECT("FIX_851","BP","ColorJSON.MAC",9)=$lb("","")
^oddPROJECT("FIX_851","BP","User.Test.CLS","cos+1")=$lb("","")
^oddPROJECT("FIX_851","Items","ColorJSON.MAC","MAC")=$lb(,"")
^oddPROJECT("FIX_851","Items","User.Test","CLS")=$lb(,"")
^oddPROJECT("FIX_851","Items","csp/user","DIR")=$lb(,"")

Converted this to draft because I'm doing more project-related work which may supersede this
