mmCEsim: Task-oriented Millimeter Wave Channel Estimation

New Features

• Single RIS channel estimation implementation (#89, PR #96)
  • Implement functions and macros concerning channel graph (#63, PR #88)
    • Multiple RECOVER for one cascaded channel (#67, PR #87)
    • Paths sorting according to number of jumps in channel graph (#68, PR #86)
    • Implement macros related to node size, beam, grid (#90, PR #91)
• Disable color output in CTest (#93)

[!CAUTION] BREAKING CHANGE: ALG function ESTIMATE now accept multiple parameters, not a single parameter anymore. Therefore, each parameter should be wrapped as $ ... $ if there is space inside.

[!NOTE] x86 and x64 binaries are built automatically by GitHub Actions; The macOS arm binary is built manually on macOS with M1 chip.

Contributed by @Teddy-van-Jerry and @mmcesim-bot, for version 0.3.0 release (#95).
