Add result errors to bw lines

* Move V3BWLine to v3bwfile.py * Add methods to V3BWLine similar to V3BwHeader * Add methods to V3BWLine to implement most of the logic in the class * Move functions related to data lines to v3bwfile.py * Add functions to generate types of erros * Add tests for the class and conftest to read results from file * Fix other tests depending on bw lines --- sbws/core/generate.py | 63 ---------------- sbws/lib/v3bwfile.py | 158 +++++++++++++++++++++++++++++++++++---- tests/lib/data/results.txt | 2 + tests/unit/conftest.py | 34 +++++++++ tests/unit/core/test_generate.py | 69 ++++++++++------- tests/unit/lib/test_v3bwfile.py | 92 ++++++++++++++++++++++- 6 files changed, 312 insertions(+), 106 deletions(-)
