feat: additional command-line arguments

this change adds the ability for seamstress to respond to the
following command-line arguments:

• "--log filename" to override the log file,
• "--log-level level" to change the logging level,
• "--test" to run Lua unit tests with busted
• "--test-dir dir" to load additional test files

this commit breaks out the setup of these features along with logging
and environment variable parsing from main.zig into args.zig,
logging.zig, and env.zig.

fix: seamstress now always uses the GPA to avoid a trace trap
spawning the luarocks process on macOS in release mode

BREAKING CHANGE: seamstress test no longer runs Lua tests,
use seamstress --test instead
