Move the functions that retrieve the supporting C library, compile an MLIR module and build a JIT execution engine to mlir_pytaco_utils. Add a function to create an MLIR sparse tensor from a file and return a pointer to the MLIR sparse tensor as well as the shape of the sparse tensor. Add unit tests.

MLIR-PyTACO: Implementing PyTACO with MLIR
TACO (http://tensor-compiler.org/) is a tensor algebra compiler. TACO defines PyTACO, a domain specific language in Python, for writing tensor algebra applications.
This directory contains the implementation of PyTACO using MLIR. In particular, we implement a Python layer that accepts the PyTACO language, generates MLIR linalg.generic OPs with sparse tensor annotation to represent the tensor computation, and invokes the MLIR sparse tensor code generator (https://mlir.llvm.org/docs/Dialects/SparseTensorOps/) as well as other MLIR compilation passes to generate an executable. Then, we invoke the MLIR execution engine to execute the program and pass the result back to the Python layer.
As can be seen from the tests in this directory, in order to port a PyTACO program to MLIR-PyTACO, we basically only need to replace this line that imports PyTACO:
import pytaco as pt
with this line to import MLIR-PyTACO:
from tools import mlir_pytaco_api as pt
