release v.16.2

🗲FLASH WITH A BROWSER🗲

Changes:

• filter bandwidths are unified across main app and spectrum, now main app uses same filters as the spectrum, before they were only using the same names so users were unaware of this issue, this should result in slighly narrower 25k, 12.5k filters in the main app mode

Reverted:

• based on user reports of weakened sensitivity on AM with the v.16, the dynamic filters are now disabled for AM modulation, and also in spectrum, now they work in USB, FM and only in the VFO and MEMORY modes
• AM desired RSSI has been reverted to match versions prior v.16 as old version shows better results in AM mode

Fixes:

• spectrum channel mode displays correct rssi bars based on current filter, before the rrsi displayed bar and rssi activated bar was different and the user had to tune much higher with the rssi trigger line, this should allow the user to keep rssi trigger line lower and thus improve ability to receive weak signals
• spectrum bandwidth change with button works immediately, before it was delayed
