scouting: Migrate to using npm-style packages for deps

Using the npm style for tracking dependencies makes it easier to write
common modules that our existing modules can import.

I was trying to set up a shared `Pipe` class for some modules and
couldn't work around this issue:

    scouting/www/entry/entry.module.ts:10:13 - error NG3004: Unable to import class PipeModule.
      The file /dev/shm/bazel-sandbox.62240ff599163761312fdbd652f7452abc23edc253dee6214f406f29dde5568b/linux-sandbox/192/execroot/org_frc971/bazel-out/k8-fastbuild/bin/scouting/www/pipes/pipes.module.d.ts is outside of the configured 'rootDir'.

    10   exports: [PipeModule, EntryComponent],

The simplest way to work around it is by using npm modules everywhere.
This meant that I had to convert the existing fbs messages into an npm
module too.

There should be no functional changes.
