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.

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.

ec339f9108 Implement CSC matrix basic API 
The CSC matrix API mirrors the CSR matrix API. However, there
are subtle differences throughout (both in the available
methods and the implementation) that I believe makes any attempt
to avoid the duplicate effort futile.

a15e78a6b7 Put COO, CSR, SparsityPattern and related types in their own modules 
This mimics how std does it, e.g. std::vec::Vec. This avoids potential
problems down the road, where adding more types might clutter the
API interface and generated documentation.

7a5f8ef1ea Redesign error handling for CSR and SparsityPattern construction 
SparsityPattern's constructor now returns a fine-grained error
enum that enumerates possible errors. We use this to build a more
user-friendly error when constructing CSR matrices.

We also overhauled the main SparseFormatError error type by
making it a struct containing a *Kind type and an underlying error
that contains the message.
