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
