Experimental lint command, HTTP crawling and other improvements

New Features

• lint command (initial Dockerfile linting capabilities with a basic set of checks)
• HTTP probe crawler (automatically probes additional endpoints referenced in the processed targets; see the --http-probe-crawl and related flags)

Improvements

• ARM64 support (need more people to test!)
• --http-probe-exit-on-failure flag to exit execution when all HTTP probe calls fail
• --include-bin-file and --include-exe-file flags to make it easier to specify multiple binaries and executables loading them from files
• xray command report enhancements
