Add prepare script to force npm publish to include built JS

[ckiee]

The latest release (1.0.1) at the time of writing, did not have a dist, so importing the library didn't work.

This fixes that so the build is always run during publish. (prepare is an npm hook)

I think this fix won't be sufficient. If you look at the npm package for 1.0.1 you can also see it doesn't include tsconfig:

$ ls -la
total 28
drwxr-xr-x 4 marek users 4096 Mar  1 13:20 .
drwxr-xr-x 3 marek users 4096 Mar  1 13:20 ..
drwxr-xr-x 2 marek users 4096 Mar  1 13:20 src
drwxr-xr-x 3 marek users 4096 Mar  1 13:20 test
-rw-r--r-- 1 marek users 1100 Mar  1 13:20 LICENSE.md
-rw-r--r-- 1 marek users 1967 Mar  1 13:20 package.json
-rw-r--r-- 1 marek users 1212 Mar  1 13:20 README.md

Thus Running build script will fail:

> tsc --emitDeclarationOnly

The tsconfig doesn't have to be included since the intention is to have it include a precompiled build in the released NPM package. prepare runs at publish-time, you're thinking of postinstall which runs at install-time.

[turboMaCk]

right you're correct I thought of post install.

I wonder if you plan to fix the issue and publish fixed version which includes compiled assets @dhkatz?
