Major Bug Fixes and Improvements (PR #62)

- Patched  build-script sysroot:
	- Extended build-script sysroot patch to `RTBuilder_32b` and `RTBuilder_64b`.
	- Replaced incorrect `RPI_TYPE` with `FOLDER_VERSION`.
	- Replaced `OS_TYPE` with `RPIOS_TYPE` in `RTBuilder_64b.
- Added Buster/Stretch OS support for 64-bit envs:
	- Added Buster and Stretch native support for `RTBuilder_64b` build script.
	- Updated CI Bash scripts with new `-o` flag to support OS selection.
	- Updated YAMLs to include buster & stretch Pi OS support.
	- Updated and added new docs.
- Strip compiler executables and minor fixes: (Patch by @visglz) 
	- Strip on compiler install: This drastically reduces extracted size from 1.7GB to 477MB
- Added Verbose Flag for debugged output: (Patch by @visglz)
  - Set "set -eo pipefail" at top of script. Set "set -v" only for verbose
      mode
  - Fix wget download of Linux kernel: The output of `wget` was failing because of multiple lines. Only consider
          topmost line with most recent file)
- Removed superfluous line: (Patch by @visglz)
	- "set -eo pipefail" is already set at top of script.
- Updated strip patch for all bash-scripts for smaller binary size.
- Updated assets.
- Updated docs.
- Fixed Minor Typos and additions in Docs
