Hardcoded invalid dataset location in the npm dist

[thefill]

It seems like your build script for dist package is messing with paths.

"propel@3.2.0" from npm contains lots of lines like this one:

var __dirname = "/Users/rld/src/propel/src";

Which causes errors when loading datasets.

[brandly]

can confirm.

const { dataset } = require('propel')
dataset('mnist/train')

Using DL backend.

@thefill @brandly It's taken a while, but we've finally cut a new release (v3.3.1) and it should work.
