Parcel locker locations about osmalyzer

Venipak also has pickup points at Drogas and Virši stations.
If we aim at mapping pickup stations for networks, they should be added too.

As I understand Unisend is an umbrella for parcel lockers branded as Unisend and Unisend uDrop.
Site in the description only has later ones.

As far as I can tell, unisend.lv has its own map with both lockers there. But my laptop prevents me from accessing that site: it considered a security threat (don't have details as to why).

So there are parcel lockers by operator/company Unisend. Local company Unisend Latvia (owned by Lithuanian Lietuvos paštas). Yellow/some green. These don't have additional branding (or it's just "Unisend").

Then there are parcel lockers by operator/company uDrop. Local company Udrop LV. Green/white. These do not themselves operate a parcel network, but other delivery network operators can use these as drop-off/pick-up points. In Latvia, AFAIK, currently, only Unisend is using them and all parcel lockers are also prominently (confusingly) advertised as Unisend.

So technically, I guess, we should only be parsing the delivery network operator delivery points (parcel lockers) - Unisend, in this case. If they happen to use uDrop, then we can add/count and verify uDrop-specific lockers for them too. Luckily, Unisend lists and differentiates their uDrop lockers on their site.

At the same time, we can parse and check uDrop lockers, regardless of what delivery networks are using them - basically see if any are missing or mistagged. But not assume they are part of any specific "brand". I guess this will avoid a terrible mess in case more companies start using uDrop.

I made a separate issue at #59 for these as they have their own "problems". I will implement the main logic and LP (also Itella?) points for now.
