Modernized svg-font-dump

[renarsvilnis]

Hi,
came accross your module today, it did what I needed it to do. Thanks for it!

But there was a DeprecationWarning: Calling an asynchronous function without callback is deprecated. due to the module not being updated last couple of years. After inspecting source, I found out that fs.writeFile without a callback. I forked & cloned the repo and fixed the issue and also did a refactor of the entire module and here is a list of what I did:

• Migrated from jshint to eslint using semistandard config
• Extracted helper functions into individual files
• Dropped lodash in favour of ES6 features which is supported in current LTS node and beyond
• Rewrote fs operations in async which resulted glyph write operations to run concurrently. Thus performance gains (not really needed, but still)
• Separated the module into 2 parts - cli and module. Now you can use it as before through cli but also if needed call it programmatically require('svg-font-dump').
• Renamed cli arguments lower dash (_) symbols to dash (-) symbols some_argument => some-argument make it more consistent as other cli applications Only breaking change for existing users
• Updated make file to reflect linter change
• Updated README to reflect changes

Suggest bumping the module to v2.0.0.

Hope the changes are welcomed! 👍

Sorry, this project is critical for old-fashioned fontello fonts repos, and need to be in frozen state. Until someone find time (never) to fix all that chaos. Please, do a fork.
