Alignment of Filters in `dwt` and `wavedec`

I am trying to implement a matrix form of the DWT (for MCMC sampling reasons) and am comparing to `pywt.dwt` and `wavedec` (v 1.3.0) to confirm that I have constructed...

This is rather a wish than an issue. Could the `lower_bound` and `upper_bound` attributes for `ContinuousWavelet` be more conspicuously specified and available? The `__init__` method does not provide a way...

Draft because it requires a future version of `meson-python` (xref https://github.com/mesonbuild/meson-python/pull/681). Changes: - Use an SPDX license expression - the `AND` for MIT and BSD-3 is a little annoying (MIT-only...
