Giacomo Vercesi 8a780a58aa GraphQL: return binaries in b64

This change fixes the pipeline behavior when producing targets:
* produce and extract now return rp_buffer, which has a start pointer
  and size
* the python api `revng.api` will return on produce/extract either str
  or  bytes depending on the mime type of the container
* the GraphQL api will encode bytes in base64

MIME types

MIMEs describe the content of the container in its entirety (not what's contained within)
Trying to conform as close as possible to RFC2045 and RFC6838
Types:
- text/*: the output will be opened in a text editor
- everything else: the output needs to be managed by an "external application"
Base MIMEs:
- Built-in MIMEs:
  - application/x-executable -> a binary
  - application/x-object -> an object file
  - text/plain -> Plain text file
- Custom MIMEs:
  - text/x.c -> C
  - text/x.asm -> Assembly
  - text/x.yaml -> Plain YAML
  - image/svg -> svg
  - text/x.llvm.ir -> LLVM IR
  - application/x.llvm.bc -> LLVM Bitcode
Mimes that are not text/* or image/svg will be transmitted over GraphQL via Base64 encoding
Suffixes (order matters):
- +ptml LHS is wrapped in PTML
- +yaml LHS is wrapped in a YAML dictionary with keys being functions metaaddresses (soon: locations)
