Support TS default import

[KilianKilmister]

Quoting from #28:

It's up to other tools to follow what TS supports.

TS also suports default imports, but yout packages definition sais it doesn't

This is a CommonJS package (like most packages on npm), so it's recommended you use the require syntax for that. However, there are TS settings to override it and let you use normal import syntax with this package too. I'm following the advice of the TS team on this.

I read the thread and yeah, it sounds reaonable
