gh-35211: Add skew Hadamard matrices up to order 1000
    
<!-- ^^^^^
Please provide a concise, informative and self-explanatory title.
Don't put issue numbers in there, do this in the PR body below.
For example, instead of "Fixes #1234" use "Introduce new method to
calculate 1+1"
-->
### 📚 Description
This PR adds constructions for all known skew Hadamard matrices of order
up to 1000. The following changes have been made:
- more skew Supplementary difference sets have been added
- The functions for supplementary difference sets in
`difference_family.py` have been changed so that now they also return
the group to which the sets belong. This makes the functions consistent
with the others contained in this file, and makes them more efficient.
- Added construction of skew Hadamard matrices from complementary
difference sets (and construction for complementary difference sets).
- Added construction of skew Hadamard matrices from amicable Hadamard
matrices and Orthogonal Designs (and construction for some amicable
Hadamard matrices).

Note that only commits from c0eb0c1 are
new, the older ones where created in #35059.
