Add Gain_TX control to the Replay App

Current Replay App , shows in the user menu a UI to select two kind of controls for the RF output level :
1-) LNA GAIN (0..40 ) dB => but it has no TX effect because it is the RX-LNA . GAIN
2-) RF AMP (0 / +14dBm , (that was correct , we have two IC's , RX / TX ) (sw is controlling weill .

Note, although SW Version 1.40 do not leave to control drictly the GAIN TX
, that Replay App , in fact, it was using the inheritated selected GAIN TX from any previous usage of MIC App.

That Pull request alllows now to have the following controls
1-) GAIN TX (0..47 ) dB (now it is OK
2-) RF AMP (0 / +14dBm , (that was correct , we have two IC's , RX / TX ) (sw is controlling weill .

Remakrs : After the change , now we can control the GAIN TX , but not "in the fly" . When we are in the Replay loop , any change of the FREQUENCY or GAIN TX will be ignored , till we play STOP / START the loop again. (but the AMP RF (0 /+14 dBs) it works in the loop withouth any problems (same as before ) .
