Addition of new TsTest and CI workflow

1. Some experimental features of Niederreiter class (getter for generator matrices, getter for direction numbers, Gray code-free generation of nets) have been made stable and, hence, available to a general user.
2. A new continuous integration workflow "Build tester" has been added. It automatically validates the compilation of the automatic tester for TsTests.
3. New TsTest named tstest_truedefect has been added. This test enables users to calculate the defect of a digital net, that is, a minimum t value for which a generated set of points is going to be a base 2 (t, m, s)-net.
4. tests folder has been reorganised to prepare for the upcoming set of unit tests.
5. #22 has been fixed.
