Random bigheads

[Eronheit]

hello, good job!
It would be very good to be able to generate random bigheads :D

Hey @Eronheit, if you don't set a prop in the <BigHead /> element, it will choose a random value for it, so if you want a completely random head just don't set any props.
Likewise if you're using the API to load bigheads in an <img /> element, just don't set any parameters and they will also be chosen at random. (e.g. <img src="https://bigheads.io/svg" />)
