komodo::linalg::Matrix::inverse is tested on more matrix sizes, from 1 to 20 random matrices
komodo::field tests have been double-checked
pure "recoding" tests from komodo::fec have been double-checked
end_to_end and end_to_end_with_recoding now runs for k \in [3, 5] and \rho \in [\frac{1}{2}, \frac{1}{3}] with n = \lfloor \frac{k}{\rho} \rfloor
all "k among n + t" combinations are tested with try_all_decoding_combinations, possibly with some removals in case recoding is involved with is_inside
Important
on my machine, make test goes from less than 8sec on latest main to around 40sec with this MR
