Wrong type in json

Here https://github.com/ebroecker/canmatrix/issues/102 not only the internal representation but also the json export itself were changing. That lead to

"factor": str(signal.factor),
"offset": str(signal.offset),
"min": str(signal.min),
"max": str(signal.max),

In my opinion it is okay to handle it internally as a different type but json allows floating point numbers, so why not use it? The change basically requires everyone using such an exported json to convert the string back to float.

May I ask why this was changed? Any chance to revert the export back to using float instead of string?

Ok, I understand now. How about adding a --useNativeTypes argument that basically does what the name suggests: use native data types of the output format?

By default it is all strings (which we should mention in the docs) and if that arg is given you use whatever the output format allows.

OK, I’ll implement it as soon as I have time. (likely in the next few days). I will only add that option to work with json though, we can expand it as needed.
