Updated requirements to work with meshtastic 2.6.2

[Y2Kmeltdown]

Just recently tried using this docker image but found I was getting the error "Exception: This version of meshtastic-python requires device firmware version 1.2 or later. For more information see https://tinyurl.com/5bjsxu32".

I know this error wasn't correct as I was using the latest firmware so I suspect the version of meshtastic-python is outdated for current stable meshtastic firmware versions. I updated the requirements and successfully built the docker image and have a version running on my own machine where I can successfully make API calls. I haven't tested all API calls to confirm they all work correctly but it appears to be working.

@Y2Kmeltdown
If you can get the tests passing again I'll happily merge it back in, otherwise I'll look at updating it and fixing test when I get back from a work trip in a couple of weeks.

Based on the error message in the CI/CD, it looks like the Meshtastic Python API might have changed, and may require a bit of involvement.

Sorry it took me so long to get to it, I have yet to do extensive testing outside of previously written unit tests, but I'm working through 2.6 updates now.

No stress for my purposes the fork has been working with no issues for the last few months. If you need help with testing anything let me know.

Sorry, I forgot to close this out when I pushed the commit.
Should be resolved with latest commit.
