[chirp_devel] Clarification about the implementation of template.py

[lhacc]

Hello, it seems that there's a problem in the implementation of
template.py, or perhaps I'm not understanding it correctly.

self._memobj is populated in the self.sync_in function, but that
function is only called when the image is downloaded from the radio, and
not when a file is loaded by hand. In other words, the template.py
implementation will crash when a file is loaded because self._memobj
won't be defined by the time the memories are read.

It looks like most radio drivers have fixed this by populating
self._memobj in a function called self.process_mmap, and then calling
self.process_mmap from self.sync_in.

Greetings
