Ray-caster: add a frame time monitor
...
It's time to start optimizing. Frame time is easy to measure, and we can
use it to gauge responsiveness.

Ray-caster: switch from draw effect to animation loop
...
This wastes a lot of CPU time, as explained on lines 253--258 of
`main.rs`, but it's better than the previous version, which could block
graphics updates system-wide for seconds on end.

Automatically generate externals.js from package-lock.json
...
This commit adds a utility to parse package-lock.json and write the proper
contents of externals.js to standard output. In addition, if the utility
(src/helpers/pkglock_to_externals.litcoffee) is invoked with a --doc option,
it instead emits a Markdown bulleted list of all of the external dependencies.
