Update ttf2woff2 to v3 for Node v12 + support

[jleiva]

Hi!
When installing grunt-webfont in Node v12 there are some errors.

I'm using:

Node v12.0.0
npm v6.9.0
node-gyp -v v3.8.0

According to ttf2woff2 this was fixed in https://github.com/nfroidure/ttf2woff2/releases/tag/v3.0.0

Error
``

I double this request, please update npm dependencies in grunt-webfont, because we get a lot of deprecation warnings and are unable to build our projects with NodeJS v12.
Thanks in Advance, Wolfgang

I'm also encountering these errors. Please consider this issue, and #408

[pbredenberg]

Would love to see #408 get merged. It seems like the outdated packages in this project are causing node-gyp to choke and fail to set execution environment bindings. Subsequent packages that rely on native add-ons (like node-sass) during npm install don't compile either.

Further research will be required to prove that point, but using the fork from @jleider resolves build errors I'm experiencing in one of my projects.
