Description

Pre discuss in #361, this PR add options for readbytes and readtext in each class.

Also it changes a behavior in FS.open, I found this when I was investigate if there's any other thing to be changed. It seems no extra parameters are required for iotools.make_stream, and the description for options is arguments for the filesystem. So I guess it was misplaced and move options for openbin inside the function.

Just an observation, readtext is as readable as read_text. But I guess it is down to historical design decision.

And maybe it's worth adding docstrings like this too?

Question for @willmcgugan - looking at https://docs.pyfilesystem.org/en/latest/reference/base.html , should all functions that take path parameter(s) also take an options kwargs?

@tzing Sorry for potentially opening a can of worms... :confused: Your PR looks great so far IMHO :+1:
