feature: added jsluice based javascript parsing to default

[Ice3man543]

Adds jsluice based javascript parsing to gather links from pages on default runs. The functionality is enabled by default and allows gathering various kinds of javascript links.

An example run on public-crawl-maze javascript interactive section

Command to run:

./katana -u https://security-crawl-maze.app/javascript/interactive/  -v -d 3

TODOS:

• Improve parsing
• Add docs to readme

Note:

• high memory uses (jumped from 150MB to 2GB)
• improved endpoint discovery
• headless mode still needs to be tested.

lgtm implementation! - marking as request changes as docs need to be added.
Note: High memory consumption might require upstream library modification
