* makefile wip * feat: adds Makefile Adds a `Makefile` for managing build-related tasks. * chore: updates dependencies * chore: updates dependencies * chore: updates bin scripts - Removes `build_release.sh` - Places deprecation notice in `build_devel.sh`, as its purpose has been superceded by the `Makefile`. * chore: updates bin scripts - Removes `build_release.sh` - Places deprecation notice in `build_devel.sh`, as its purpose has been superceded by the `Makefile`. * fix: Makefile Makes several corrections and improvements to the `Makefile`: - Previously, the `ifeq` rules were not behaving as intended, due to false assumptions regarding how `make` fundamentally behaves. Malfunctioning imperative-style programming has been replaced with declarative rules to repair this issue. - Previously, all release executables were zipped after compilation. In order to spare non-Windows users from (possibly) needing to install a package to unzip the executables, all non-Windows binaries are now compressed with `gzip`. (Windows executables are still compressed with `zip`.) - Removes a bit of needlessly verbosity in several rules and paths. * chore: updates dependencies * chore: bumps version to 3.3.1
