fix(compiler): relax compiler settings for capnpc-js (#84)

This glosses over the fact that the compiler will always emit `import * as capnp from 'capnp-ts';` regardless of whether that import is actually used. Unclear if that import statement is the way to go in the future, vs. just importing the parts that are actually needed for the schema.

Closes #83.
