Add prv alterations
Add a 'previous' field in both database and static data.
This field can be used to infer when each alteration took place (maybe in the previous version or in 3 versions ago for the current sequence).
Each alteration element is a mask where:
- the last X bits represent how many versions ago was the update
- the remaining bits represent the id of the altered basepair (i.e. between 1 and 40.000)
Change the way how the results are printed in freq_bp query. Now, we are getting a distribution of how each bp was edited in the past (e.g. '33% T>C').
add unit tests and integration tests to validate the new changes
