REL: glass 2023.7 (#123)

glass 2023.7 (1 Aug 2023)
-------------------------

* New radial window functions `linear_windows()` and `cubic_windows()`,
which correspond to linear and cubic spline interpolation of radial
functions, respectively. These are overlapping window functions, and it
has been difficult to obtain accurate matter power spectra so far.

* The `partition()` function now returns an array of weights to
approximate a given function by the window functions. This is necessary
to obtain an accurate fit of redshift distributions by overlapping
window functions. For example, to get the array of galaxy densities in
each shells from `dndz`, one would now do:

      ngal = partition(z, dndz, shells)

* A new function `getcl()` was added to return angular power spectra by
index from a list using GLASS ordering.

* The `gaussian_phz()` function now accepts bounds using `lower=` and
`upper=` keyword parameters.
