Compare TUV-X Tridiagonal Solver Code with LAPACKE's implementation

[AdityaDendukuri]

1. Tests involved generating random matrices in both single and double precision across various sizes (ranging from 1000 to 10,000,000).
2. Added a benchmarking directory in the project that uses google benchmark for evaluating runtimes for solver code.

Closes #91
