Fix /types regeneration when using npm run watch

[tniezg]

Context

Related to #63. After initial bundle, every .ts file with just TS interfaces gets ignored. Since we started clearing /types before bundle regens, these files end up missing when developing the SDK and cause errors.

Expected Behavior

• Force Webpack to regen all .d.ts files, including those with just interfaces.

Possible Fixes

A. add generic import <...>.ts everywhere an interface file is loaded (maaaany places)
B. somehow fix how Webpack regens /types, but difficult due to issues reported in #63
