* Adjust doxygen configuration to search correct paths
* Adjust CMake configuration to use new include paths

* Add delivery_series_sync function to download previously delivered files from artifactory

* delivery_gather_tool_versions now returns non-zero if unable to determine a tool's version

* Add helper function have_spec_in_config()

* Break delivery.c into smaller components

* Adds --cpu-limit and --parallel-fail-fast arguments
* Adds disable, parallel, and setup_script keys to [test] blocks

* Continuation of #19

* Fixes always_update_base_environment override bug added by PR #19

* Finish type hinting implementation

* ini_getval_* functions now able to affect rendering mode using INI_READ_RAW and INI_READ_RENDER
* Created pointers to deeply nested structures to increase readability
* Output from ini_write() is more consistent, with fewer errant spaces and line feeds
* Fixes accidental regression in #19. INIVAL_TYPE_STR_ARRAY never produced an array of pointers to char. This needs to be corrected in the future. i.e. It has always generated a new-line delimited string, not a StrList, or array.

* Fix strlist_append_tokenize

* original pointer is no longer modified
* token strings are stripped of leading space before appending to the list

* Use defines instead of magic numbers

* delivery_init: add render_mode argument

* test_conda: Add render mode

* test_ini: Add render mode

* Only add conda packages and wheels to the image

* docker images are saved to the packages directory and will be consumed by the image if present.

* Implements get_github_release_notes()

* Remove unused variables

* Fix circular dependency on tplfunc_frame

* Remove predeclaration of tplfunc_frame
