fix: cli temperature read

changes:
- fix: read temperature values without daemon
  Add subcommand to read temperature values without starting the daemon

- fix: implement measured value types
  Replace measured value types with constants

- fix: add sensor pipelines
  Add functions which returns a channel with measured values

- fix: filter measured values from a channel
  Add functions to filter measured values by sensor id or measured
  value types.
