📋 Changes

• Mark three functions as `static inline`.
• Make adjustments to the default `CFLAGS` in the `Makefile`.
• Update the CI configuration and the CI badge in `README.md`.

⚡ Performance

• Let colors enabled and ASCII (as opposed to EBCDIC) be the "happy path" that the code is optimized for.
• Do not check `hextype` in multiple locations. Check it once in `main` and then call the right function.
• Refactor several if-expressions and switches.
• Mark several functions as `inline`.

• Remove unused variables and function arguments.
• + 2 more

📦 Tooling

• Add a `profile` target to the `Makefile`.
• Add a benchmark script for Python 3 named `bench.py` that confirms that the performance is mostly IO-bound, and also outputs a couple of graphs by using `gnuplot`.
• Add GitHub action configuration for benchmarking, generating Markdown and graphs and committing the results to the `main` branch.
• Move the functionality of the `release.sh` script into the `Makefile`, and remove the script.
• Add support for fuzzing by running `make fuzz`, by using `afl-gcc` and `afl-fuzz`.

📦 `main.c`

• Remove an unused function call (ref #1, thanks @Harazi).
• Use a `switch` instead of `if`/`else` in `get_ascii_char` and `get_ebcdic_char` .
• Rename `pname` to `program_name`, `fpi` to `input_file` and `fpo` to `output_file` .
• Let `output_file` be global, and use char literals instead of numbers (ref #2, thanks @oliverkwebb).
• Let the `input_file` be global.
• Let the variables `COL` and `LLEN` be defines instead of `constexpr`, to support versions of C before C23.
• Use `boolean`s instead of `int`s, whenever possible.
• Remove the `perror_exit` function, but let the `error_exit` have the same functionality if no message is passed in.
• + 4 more

📦 `Makefile`

• Add tests.
• Add a `fmt` target to the Makefile that calls `clang-format` and formats the source code.

• Support macOS.

📦 Various
