impl<'de> MyDeserialize<'de> for BinlogRow

type Ctx = (u64, &'de BitSlice<u8>, bool, &'de TableMapEvent<'de>)

Content:

number of columns
column bitmap - bit is set if column is in the row
have shared image - true means, that this is a partial event and this is an after image row. Therefore we need to parse a shared image
