The current implementation samples log(n) challenges to construct the EqPolynomial. It was noticed that only 1 challenge is necessary since we can take the log(n) square powers: tau, tau^2, ..., tau^{2^{log(n)-1}.

refactor: Optimize tau generation with PowPolynomial in snark.rs
00e8350 
- Imported and implemented `PowPolynomial` into `src/spartan/snark.rs`,
- Simplified and optimized `tau` variable generation using `PowPolynomial`, decreasing the transcript use,
- Adjusted `tau` variable generation method in `prove` and `verify` functions

Fixes lurk-lang#155
