Some devices are sensitive about the type of write performed. Add support for choosing whether or not a response is requested.

Thanks for your PR! It's important that we don't break existing projects using this library. Since this parameter was previously not specified, what is the default value of type
if omitted?

As I read the PR, the PR proposes the write_value()
function to receive a new optional parameter with_response=True
and thus existing code not providing that explicitly will get the default of True; in turn that will set write_type
to "request"
and that is then given to type
if omitted.
So, that is the long story; and in short: existing code would with this PR default to 'type': "request"
(as they will default to the with_response=True
parameter.

write_type = 'request' if with_response else 'command'
might be more appropriate here, or if more explicit code is preferred:
if with_response:
write_type = 'request'
else:
write_type = 'command'
