Add method to capture doctype=A95, "Production and Generation Units"

[henri-chat-noir]

Excellent package -- awesome someone has been working through this mess with these XML files. However, I could not see that this was covered. Nor did a search on "A95" show anything on repo (that looked connected to documentType).

As anyone who's worked with trans platform for more than a day knows, access to "Master Data" is a real challenge. There is, wait for it, one (lol) report in the section on the user guide, "Production and Generation Units"
https://transparency.entsoe.eu/content/static_content/Static%20content/web%20api/Guide.html#_master_data

Sample API URL in guide is:
GET /api?documentType=A95&businessType=B11&biddingZone_Domain=10YCZ-CEPS-----N&implementation_DateAndOrTime=2017-01-01

This is a crucial report, as it is one of the only (direct) ways I can see to associated "W" class resources with "X" type market participant codes. From W to X to Vat No., then owner/company details, etc.

Easy enough for me to hack something up as a fork, but be good if it was in main stream. I'm a crap hacker, but will mimic what's been done for new method (on the raw client) in my fork and will figure out a parser, drawing also on approach in place already. Let me know if any interest in working from my code.

P.S. Small point, but you have some methods covered not included within the overview on the main page. Just heads up, as sort of thing useful to newbies.

UPDATE: Still likely makes sense to include this API in the library, for completeness if nothing else. It also does seems to have some useful information, e.g. I think may valid source of a generating units 'online date' via the <implementation_DateAndOrTime.date> attribute that is returned.

However, sadly, presumably for many of the smaller operators, it's the intervening TSO (or other intermediary) that's listed as the "Market Participant" X-code. It may be just as well to use the "EIC Responsible" field in the XML download from static info on ENTSOE site to get 'owner' information, which could well be the same code. (Perhaps both sources may need to be queried, uggh.)

hi @henri-chat-noir this seems like an interesting idea, however I am not entirely sure what the data exactly is. Can you expand a little on what "master data" means in this instance?
