COO: add push_matrix fn
...
- This function allows one to add entire dense matrices
to a sparse COO matrix.
- Added a small mention of this new function in the
example in lib.rs

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.

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.

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.

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.

The CSC matrix API mirrors the CSR matrix API. However, there
