Feature Request: asn1js support

[driverkt]

Hello, I'm interested in support for asn1js (or a similar decoder). A few notes:

• The output is pretty whitespace sensitive -- does this pose an issue with the goals of Boop? How would Boop represent a tree view?
• Is it possible to include a "library" into a script? Are you allowed to reference something from a CDN, or is that discouraged?

References: asn1js and dumpasn1.

@IvanMathy Any comment on including dependency scripts from npm or a CDN? The documentation for Modules doesn't seem to make this clear (or it implies only local includes are permitted).
