OTA firmware update fails when updating to version greater than 3.9

[nseidle]

Problem: If you load v3.9 and attempt to firmware update to v3.10, it says it's up to date.

RTK Firmware uses a Major/Minor semantic versioning system.

The current firmware update method is doing a blind

if x > y 
    then firmware is newer

This is bad because

3.9 > 3.11

Which in terms of versioning, is wrong. v3.11 is newer than v3.9. We should be comparing major/minor versions separately, not as a float.

Users who are using a lower version will have to use the GUI or CLI methods to get to v3.11 where the fix will be in place.

Fixed in v4.0. If you've got an older firmware version, you'll be able to get to v4.0.
