Crossing out the entries that require no change, or can be done in the future

Added

• IntraTwoOpt local search operator (#706) internal
• description key for unassigned tasks in output, if provided (#403) changes in json output, not cpp code
• location_index key for unassigned tasks and each step, if provided (#625) changes in json output, not cpp code
• Shared target to makefile, for creating Position Independent Code (#617)
• Exposing some internals for Python through compile flags (#640) only for python
• Stats on local search operators use for dev/debug purposes (#658) internal, for debugging
• Project can be compiled without routing support to limit dependencies (#676)
• Internal max_tasks constraints derived from input to speed up local-search (#648) internal

Changed

• Prune local search moves based on TW constraints (#583) internal
• Prune local search moves based on capacity constraints (#709) internal
• Refactor exception class (#639) internal change, nothing needed on our end
• CI builds now run against libosrm v5.26.0 (#651) CI changes
• Reduce computing time on PDPTW benchmarks by around 20% (#559) internal
• Change Input and parser signature to simplify downstream usage (#665): Made changes according to new Input signature
• Consider move options in SWAP* that were previously wrongly discarded (#682) internal
• Use cxxopts as command line parser instead of getopt (#602) internal
• Change polylineencoder usage to submodule instead of plain header (#686) internal

Fixed

Only three changes were needed, others were internal/optimization changes not affecting us:

• Shared target to makefile, for creating Position Independent Code (#617): Needed to change the CI accordingly.
• Project can be compiled without routing support to limit dependencies (#676): Needed to change the CI accordingly.
• Change Input and parser signature to simplify downstream usage (#665): Made changes according to new Input signature.
