Long-term PyTrx to-do list

[PennyHow]

• Better manual delineation functionality in the Area and Line objects (e.g. eliminate the risk of infinite looping)
• Faster georectification processing. This can either be done by sourcing more efficient methods, or potentially using parrallel processing
• Faster handling of DEM, so that users that input DEMs with higher spatial resolution and coverage

[PennyHow]

• Move away from gdal as a dependency
• Working examples in readthedocs
• conda installation (with conda-forge)
