1fa0de92ae Preserve column dim type in CSR * Dense
This is necessary so that CSR * Vector == Vector (before it would
also yield a DMatrix).

7a083d50f7 Increase tolerance to ensure tests pass
It's possible that some particularly bad inputs cause
severe loss of significance in the triangular solves.
This is exacerbated by the fact that the way we test
the (residual) error is also prone to loss of significance,
so that the error measure itself is problematic.

We could maybe improve this in the future by using arbitrary-
precision arithmetic to remove some sources of error and testing
against appropriate bounds.

9cd1540496 Improve and test proptest generators
Due to a bug in proptest, we were required to pull in and modify
parts of proptest::strategy::Shuffle. Once the below PR has been merged
and released on crates.io, we can remove this code.

e655fed4fa Replace Arc<SparsityPattern> with SparsityPattern
After much deliberation, I have come to the conclusion that the
benefits do not really outweigh the added complexity. Even though
the added complexity is relatively minor, it makes it somewhat
more complicated to inter-op with other sparse linear algebra
libraries in the future.

6a1d12705f Remove old .get() API for CscMatrix in favor of entry API
This essentially makes the API of CscMatrix analogous to

66cbd26702 Add prealloc suffix to spmm_csr and spadd_csr
The suffix is intended to communicate that these methods
assume `preallocated` storage, i.e. they try to store the
result in a matrix which already has the correct sparsity
pattern for the operation.
