Code optimization (#49)

* git: ingore meson files
* fix: enum -> enum class, with explicit base type
* misc: format
* fix: an unsigned must be >= 0, assertion not needed
* fix: enum classes, most value now strictly static cast
* fix: removed unused variable
* fix: properly ordered struct member initialization
* fix: marked function static
* fix: enum -> enum class : uint8_t
* fix: initialize draw type as a ref, with vec.at(), strict type case
* fix: unused var
* misc: use more parentheses for math expressions
* fix: [nodiscard] is a c++17 extension
* misc: use more parentheses for math expressions
* fix: marked structs static
* misc: use more parentheses for math expressions
* fix: marked functions static
* fix: marked some function static
* fix: comment out unused var
* fix: marked functions and objects static
* fix: static_cast most values
* fix: enum -> enum class : uint8_t
* fix: enum classes, most value now strictly static cast
* fix: removed unused variable
* fix: marked function static
* fix: unused var
* refactor: satisfy `clangd` with many `static`s
* misc: down with `anonymous-namespace` and `boost` suggestions
* refactor(tui)!: don't directly include `input.hpp`
* misc(clangd): won't suggest adding non-sense (afaik) statics
* refactor: remove non-sense `static`s
* fix: use native raw-mode management instead of `stty`; conventional error msgs; use `err()` where applicable
* refactor: perf < code readability
* fix(input): don't make << ugly
* docs(input): a comment of what were ignoring
* fix(input): unnecessary cast ruins stuff
* fix(unix-raw-mode): use `stty` as it's somehow more universal
