Add tdeck example

[NyanHelsing]

GOAL:

A simple instant message functionality: (cc @ripplebiz )
Create a single-room secure chat (room ID + user ID can be configured at build time)

• Any t-deck device flashed with this firmware will be able to communicate in that room.
• The UI is text-only, and shows a history of messages insofar as they fit on the screen.
  • after a message rolls off the screen it is not recoverable; there is no screen scrolling horixontal or vertical.
• The bottom most line of text displays the message the user is currently typing; its length is limited to the screen width.
• a new message displays on the line second from the bottom, and older messages are pushed up.

TODO:

• Need to move tft lib to the examples dir
• would like to run the t-deck example with platformio + project dir arg
  • giv the example dir its own platformio.ini + copies of board config
• need to finish adjusting the config to work for t-deck board (helpers files aren't working yet)
• need to actually get mesh instantiated for t-deck
• need to write a data model to hold the messages that are presently displayed on the screen
• need to write a view to actually render those strings to the display + wrap messages as needed.

DONE:

• adds board config + deps for t-decks (non plus)
• adds build scripts to build && flash to a t-deck
• need to bring in the lilygo copy of the tft library since they made modifications to the init script

can we get linter config? this'll be noisy if editors can't be consistent.

WIP:

Right now wehen i try to build with platformio run -e T-Deck, i get:

Ok grabbed the example from the tdeck repo; just need to figure out how to merge the bins now? any pointers would eb great; i see the merge-bins file and am comparing it with the one in the meshatastic firmware repos as well

[NyanHelsing]

i added the espi_tft library; todo will move that into example/tdec-example/lib (need to figure out how to adjust the platformio.ini to make that work first
