Implemented TactilityKernel and DevicetreeCompiler, updated licenses & copyrights (#452)

**New features**

- Created a devicetree DTS and YAML parser in Python
- Created new modules:
  - TactilityKernel (LGPL v3.0 license)
  - Platforms/PlatformEsp32 (LGPL v3.0 license) 
  - Platforms/PlatformPosix (LGPL v3.0 license)
  - Tests/TactilityKernelTests

Most boards have a placeholder DTS file, while T-Lora Pager has a few devices attached.

**Licenses**

Clarified licenses and copyrights better.

- Add explanation about the intent behind them.
- Added explanation about licenses for past and future subprojects
- Added more details explanations with regards to the logo usage
- Copied licenses to subprojects to make it more explicit
