Possible typo in Ethos/ecu/main.lua and OpenTX/LView/LView.lua

[isbear]

Hello.

While just browsing I encountered a 'null' keyword in the lua file: https://github.com/RealTadango/FrSky/blob/fb8e450f8e15eb8d9f1fe3496498a30254764ad2/Ethos/ecu/main.lua#L138

Grepping the project found two other instances of 'nill':

• https://github.com/RealTadango/FrSky/blob/master/OpenTX/LView/LView.lua#L549
• https://github.com/RealTadango/FrSky/blob/master/OpenTX/LView/LView.lua#L591

I think this should be 'nil', not 'nill'.

P.S. This does not affect functionality, since non-existing vars just return nil.
