Add: add multiple files argument ; Add , PIN: add arguments from IPFS docs

[Zer0C001]

Allows for new usage:

from ipyfs.ipfs import IPFS
ipfs=IPFS(init_self_attr_RPCs=['add','pin','cat','ls'],response_return_status_code=False)
### now we can call ipfs.add instead of making a new Add object
### ... 
### ipfs add -r : 
result=ipfs.add(files={ str(Path(i[0],j)): (str(Path(i[0],j)) , open(Path(i[0],j),'br')) for i in Path(the_path).walk() for j in i[2]})
ls=ipfs.ls(result[-1]['Hash']) ## result is list, last element is the top directory

changes:

• IPFS:
  • __init__: added arguments
    • response_return_status_code: passed to _response
    • init_self_attr_RPCs : add RPC objects as attributes to the IPFS object ( changed __init__ on multiple classes to allow for that )
  • _response:
    • argument response_return_status_code: if set to False return just result, since we raise an exception if response.status_code != 200 anyway
    • try to parse result as multiple json lines ( returned as list ), eg. when adding multiple files
  • _send : add argument files dict
• Add : added arguments :
  • to_files: Add reference to Files API (MFS)
  • pin_name: Name to use for the pin
  • files: add multiple files
• Pin: added arguments :
  • add:
    • name: An optional name for created pin
  • ls:
    • name: Limit returned pins to ones with names that contain the value provided (case-sensitive, partial match). Implies --names=true.
    • names: Include pin names in the output
