RFC: CODA import statement
CODA is a statement electronic format defined by febelfin
https://www.febelfin.be/sites/default/files/files/standard-coda-2.5-en.pdf
It is supported by most of the Belgium banks.
I started to write a parser for it at https://codereview.appspot.com/324150043/
And with #5882 (closed), as we can easily create statement from parsed files, we can have a standard module which parse this format.
