escape characters in URI's

[lklic]

we have a lot of escape characters in the URI's:

That is because in the MIDAS data, the ID for different levels can look like :

<a5001>00001333,T,001,T</a5001>

<a5002>00000090,T,002,T,001</a5002>

<a5003>00012395,T,002,T,002,T,001</a5003>

and it escapes the comma.

I don't think we should hash them and lose the id, however we could probably remove the comma with ETL.

Need to consider this because it created many issues. We most probably will have to normalize it by choosing an other character than ,
