Support for different basis functions

[gjgilbert]

A nice feature would be to be able to specify the desired wavelet basis function with a simple keyword, e.g. "morlet", "ricker", "paul"

I'm not sure if this is possible under the current (projection) framework. It works for a Morlet wavelet because you can decompose the complex exponential into the sine and cosine components (for the projection) and have the other part as a weight. But neither the Ricker or Paul wavelet possess that complex exponential for the decomposition, so there is no easy basis function to use.

Ah, yes, that makes sense

It's not necessarily a problem though, because if the non-uniform FFT parts work then we can readily include extra mother wavelets 😃
