Address PR brainflow-dev#799 review comments and add ANT Neuro RX-300 EDX board

- Remove EDX=3 from IpProtocolTypes across all 8 language bindings (EDX uses
  gRPC only, not a generic IP protocol variant)
- Restore accidentally removed `using System.Runtime.Serialization.Json;` in
  board_shim.cs (fixes DataContractJsonSerializer compile error)
- Replace verbose EDX build docs with a single brief CMake note; emit
  FATAL_ERROR with install instructions when gRPC/protobuf not found
- Collapse SupportedBoards.rst EDX examples to one per language; remove
  ip_protocol and master_board references; add RX-300 subsection
- Add #else block in board_controller.cpp so EDX board IDs return a clear
  error when BrainFlow is built without -DBUILD_ANT_EDX=ON
- Separate impedance channels into ancillary preset in clone_ant_edx_board;
  default preset now contains only EEG/streaming channels
- Strip params.master_board cross-check from ant_neuro_edx.cpp (no longer used)
- Add ANT_NEURO_RX_300_EDX_BOARD (id=81) as a self-contained EDX-only board
  with direct JSON config (4 EEG + 4 EMG + 17 aux channels, 500 Hz); no
  hidden legacy master board entry
- Make board IDs contiguous: close gap at 67 by shifting EDX series from
  68-82 down to 67-81; update LAST sentinel in all bindings
