Wrong timestamps H_GRONINGEN dataset on movebank

[milotictanja]

The Western marsh harriers from Groningen are migrating into the future as some records have future timestamps. The dataset downloaded from movebank contains the following date ranges:

animal-id	number of observations	min date	max date
5446465	178914	2012-01-06	2018-07-07
5336455	5420	2014-04-06	2015-11-06
5325667	781906	2014-01-08	2020-07-05
5327085	21337	2016-01-07	2018-07-08

While the date ranges in the UvA-BiTS dataset is as follows:

animal-id	number of observations	min date	max date
5446465	178914	2012-05-10	2016-08-11
5336455	5420	2014-06-04	2014-06-23
5325667	781906	2014-07-04	2018-07-11
5327085	21337	2016-06-18	2016-09-03

For individual 5325667 future dates are recorded. For all other individuals dates are shifted as well (different min and max dates in movebank and UvA-BiTS datasets). The total number of records doesn't differ between datasets, so no new data have been added.

Let's see if addressing #119 solves this

The issue was caused by a wrong mapping of day and month (switched). I have reuploaded all files and downloaded them to check:

year	records
2012	85,309
2013	27,538
2014	85,329
2015	87,025
2016	102,280
2017	290,707
2018	309,389
Total	987,577

Which is correct with what I uploaded. The summary numbers displayed are not entirely correct though, but addressing that in #119

Note: there are no longer records in the future.
