* Support multiple formatters (#31)
Closes#31
This commit makes it so apheleia can run multiple formatters one after
the other and use the resultant output to format the current buffer.
This works somewhat like a pipeline. The output of one formatter becomes
the input to the next formatter until all formatters have run and then
an RCS patch is built from the resultant output and applied to the
current buffer.
Note: For convenience we internally represent the users configuration as
a list of formatters even when it may only be one. For example if the
user has configured `(python-mode . black)` in apheleia-mode-alist then
internally we interpret that as a formatter list of `(black)` instead of
`black` as we did previously.
