[RF] handle 64 bits values (except for UNO) (#698)

* handle 64 bits values, except for UNO
Arduino UNO is not enough powerfull to handle properly uint64_t in terms of memory so differenciate the variable type depending on the board type
With this configuration ATMega will not be able to receive with simpleReceiving 64 bits values. Of course Json will work with 64 bits values for this board.
* Simplify jsondata.success() condition
* Renamings and optimize deduplication functions
* replace 2 dimensions array by a structure so as to handle the time with an uint32_t  when using an ESP (instead of a uint64_t)
* change storeValue and isAduplicate function names
* point to the rcswitch revision with the new 40 bits protocol
