* Refactor steno into STENO_ENABLE_[ALL|GEMINI|BOLT]
* Update stenography documentation
* STENO_ENABLE_TXBOLT → STENO_ENABLE_BOLT
TXBOLT is a better name but BOLT is more consistent with the
pre-existing TX Bolt related constants, which all drop the "TX " prefix
* Comments
* STENO_ENABLE_[GEMINI|BOLT|ALL] → STENO_PROTOCOL = [geminipr|txbolt|all]
* Add note on lacking V-USB support
* Clear chord at the end of the switch(mode){send_steno_chord} block
* Return true if NOEVENT
* update_chord_xxx → add_xxx_key_to_chord
* Enable the defines for all the protocols if STENO_PROTOCOL = all
* Mention how to use `steno_set_mode`
* Set the default steno protocol to "all"
This is done so that existing keymaps invoking `steno_set_mode` don't
all suddenly break
* Add data driver equivalents for stenography feature
* Document format of serial steno packets
(Thanks dnaq)
* Add missing comma
* New feature: `DYNAMIC_TAPPING_TERM_ENABLE`
3 new quantum keys to configure the tapping term on the fly.
* Replace sprintf call in tapping_term_report by get_u16_str
* Replace tab with 4 spaces
