Subject: [PATCH] Added ability to enter custom tone values in Morse app
 (#2679)

* Added ability to enter custom tone values in Morse app

Added the ability to type in a custom tone value in the morse TX app (issue#2582)

*Click on the tone field to open a keyboard for entering in a desired value between 100hz - 9999hz.

*Maintains original step value of 20 when scrolling the rotary wheel.

* Update ui_morse.cpp

Replaced std::to_string with to_string_dec_uint

* Moved tone_input_buffer init to in-class
