Performance improvements & bug fixes

Some bug fixes and changes to improve performance.

HiDEM v2.1.0

The domain partitioning scheme has been overhauled to use METIS, making typical HiDEM simulations much faster.

CMake is now used for compilation/installation.

HiDEM v2.0.2

Bug fix - wrong argument order in raster interp calls (BIPINT)
Main issue - incorrect bed slope calculation

HiDEM v2.0.1

Bug fix - previously glas.f90 had a hardcoded undercut shape implemented. This is now removed.

HiDEM v2.0.0

Version 2 of HiDEM:

Added

- Automatic computation of domain partitioning
- 'Run Name' parameter, appended to all output data
- 'Restart from Run Name' to make restarting easier
- 'Work Directory' and 'Results Directory' for organising output
- Synthetic test case

Changed

- Format of input file (now specified as "Param Name = Value" rather than ordered list)
- Reorganise code into directories (src, scripts, etc)
- Unhardcoded density, gravity, geometry input file, etc
- Convert most source from F77 to F90
- Move to semantic versioning (2.0 -> 2.0.0)
