Unit is malformed: no such unit

[coder543]

Within the last several days, n several of my machines (all that I've tested), rink has started outputting this every time I start it:

$ rink
Unit копеика is malformed: No such unit RUB, did you mean ruby?
Unit kopek is malformed: No such unit копеика
Unit rouble is malformed: No such unit RUB, did you mean ruby?
Unit ruble is malformed: No such unit RUB, did you mean ruby?
Unit копеики is malformed: No such unit копеика
Unit рубль is malformed: No such unit RUB, did you mean ruby?
Unit ₽ is malformed: No such unit RUB, did you mean ruby?

I haven't had time to dig in and understand what's happening, but I'm assuming some upstream currency format changed in an incompatible way.

It looks like the European Central Bank deleted the Ruble from their currency data. I can probably fix this on the backend side by including a hardcoded value for Ruble <-> Euro.

According to the ECB:

Owing to current trading activity in the EUR/RUB market, the European Central Bank (ECB) is not in a position to set a reference rate that is representative of prevailing market conditions. The ECB has therefore decided to suspend its publication of a euro reference rate for the Russian rouble until further notice. The ECB last published a EUR/RUB reference rate on 1 March 2022.

Fixed in f10a39c01e8332948f1be367c559904f4ffb70f3 which should automatically roll out to everyone using 0.6+ (since it fetches the data from https://rinkcalc.app/data/currency.json by default). I actually added default values for all ECB currencies so this exact failure shouldn't happen again.

Data for the Ruble won't live update until I can find an API for it. A lot of the ones I've seen are paid access only.
