SensESP v2.7.1 released

[mairas]

Due to the broken builds caused by a new major version release of ArduinoJson 7 -- or rather, caused by SensESP not pegging ArduinoJson version to 6.x -- I've released a new patch version that pegs the version to 6.x. Several smaller changes were included as well, see the changelog here:

... and now I have also released SensESP 2.7.2 that includes a fix that was omitted from 2.7.1. My bad!
