## [unreleased][unreleased]
### Added
+- Added lf gproxii read - reads a gproxii tag from the antenna
+- Added lf indala read - reads an indala tag from the antenna
- Added lf visa2000 demod, read, clone, sim commands (iceman)
- Added markers in the graph around found Sequence Terminator after askmandemod.
- Added data mtrim <start> <stop> command to trim out samples between start and stop
- Added option c to 'hf list' (mark CRC bytes) (piwi)
### Changed

+- `lf indalaclone` has been moved to `lf indala clone`
+- `lf indalademod` has been moved to `lf indala altdemod` (reads from graphbuffer)
+- `data pskindalademod` has been moved to `lf indala demod` (reads from graphbuffer)
- `data askvikingdemod` has been moved to `lf viking demod` (reads from graphbuffer)
- `data fskpyramiddemod` has been moved to `lf pyramid demod` (reads from graphbuffer)
- `data fskiodemod` has been moved to `lf io demod` (reads from graphbuffer)
