PlatformIO kept exploding when trying to build the `microrl-remastered`
library because of the folder structure. Resolved by vendoring v2.5.0
and including our `_user_config.h` in the source folder, finally making
the compile process happy.

WIP: debugging microrl+Commander

shell-lib: use TeePrint for most outputs, Commander switches ports

shell-lib: add vendored microrl library info

shell-lib: check for cli streaming for both input ports

Moves the `adc dump` ending check into `cli_loop()` so that both streams
can be monitored. Also gets away from checking `cli->getInputPort()`
which is now a NULL to work with `microrl`

shell-lib: fixup! stop Streaming when a command is run

Too much potential for an extra character in the buffer to stop the
streaming prematurely. So, instead just wait until a command is
executed.
