Amazfit Cor: Fix recogition of new firmwares

Browse Source 
Newer Cor and Bip firmwares seem to be indistinguishable,
What we do for now is use the version we already search for say
Bip firmwares are valid from 0.0.8.00 to < 1.0.5.00 (lastest as of today is 0.1.0.39)
Cor firmwares are valid from 1.0.5.00

This should work for a while.
Fixes #1095
