v0.9.8

• Fixes an issue that caused a segfault when writing plinkfiles in Python 3 (thank you @jeremymcrae).
• Adds equality op on Sample and Locus.
• Adds CI/CD and tox.

Minor fixes

• Update Python unit tests to reflect new allele order
• Fix double free bug

Create plink files

It is now possible to create plink files.

Important changes:

• Fixed critical bug that caused the minor alleles to be associated with the wrong allele in the .bim file, allele1 instead of allele2.
• Changed so that gender (female=0,male=1,missing=-9) and affection(control=0,cases=1,missing=-9) now is 0 and 1 in the Python API. The same coding is used when writing.
