RFC 0002 for mobility extension

[schlingling]

For my new PR, i updated the RFC-files with the feedback received from #117. This iteration of the RFC hold just really minor changes compared to #117.

As discussed with @rhazn, this should be the final PR for RFC0002 so i changed the status already to ACCEPTED.

FYI @georg-schwarz , if you have major feedback please let us know.

I think we agreed solely on ArrayBuffer here:

jayvee/rfc/0002-mobility-extension.md

Line 40 in baeb09b

content: string | ArrayBuffer //The content of the file as a string Or maybe a byte array instead

---

Note that there are two remaining "tbd" in the RFC:

jayvee/rfc/0002-mobility-extension.md

Lines 46 to 48 in baeb09b

	export interface FileSystem {
	tbd
	}

jayvee/rfc/0002-mobility-extension.md

Lines 54 to 56 in baeb09b

	export interface None {
	tbd
	}

---

This question should be removed:

jayvee/rfc/0002-mobility-extension.md

Line 143 in baeb09b

Not sure, how to *implement* multiple input/output of blocks (for SQLiteSink and ArchiveInterpreter)?

---

Otherwise I think this is good to go 👍

removed the tbd, commented by @felix-oq and pushed to that branch again. Changed tbd to code comment as discussed with @rhazn.
