Litecoin: Change serialization of tx in cache, #770

Browse Source 
It is necessary to remove all transactions from the cache DB column
using command like
`/opt/coins/blockbook/litecoin/bin/ldb --db=/opt/coins/data/litecoin/blockbook/db --hex --column_family=transactions deleterange 0x00 0xffffffffffffffffffff`
or do full db resync. The old data in the transaction cache are not compatible.
