Add K155ID1 / К155ИД1 BCD-to-decimal decoder

[dbrgn]

These are mainly used for driving nixie tubes.

SUMMARY

• Add sym/cmp for 74141 ICs
• Add dev for K155ID1, the Russian (USSR) version of that chip which is easier to source than the original 74141s

The Belarusian company Integral still produces K155ID1 chips: https://integral.by/produktsiya/integralnye-mikroskhemy/standartnye-tsifrovye-logicheskie-ims/ttl-seriya-k155-ekf155/k155id1.html Not sure if these are completely new, or some kind of NOS repackaging. These chips can be obtained from Ebay and similar sites.

Here's a datasheet that describes how the IC works: https://tubehobby.com/datasheets/k155id1.pdf (This is neither the 74141 nor the one by Integral, but it should behave the same.)
