pass boundary types to dynesty

[ahnitz]

This passes the pycbc boundary types (where applicable) to dynest. Only the two-sided reflective and the cyclic boundaries are supported as those are the only ones Dynesty has. So, notable, there is no one-sided reflective boundary.

Example of how to write the boundary in the config file. Note that if you specify the boundary type, you also need to explicitly
set the min/max of the parameter as well. I am doing so here for inclination. The units are currently radians per PI, but that will change to PI in #3355, so be careful until that patch is applied.

#btype-min-distance = reflected
#btype-max-distance = reflected


[prior-inclination]	[prior-inclination]
name = sin_angle	name = sin_angle
cyclic-inclination =
min-inclination = 0
max-inclination = 3.141592653

For sanity, let's say this depends on #3355

I didn't know Dynesty supported cyclic and reflected boundaries. Finally, a use for them! Anyway, looks good.

Look good to me, thanks.
