Byte order in can dbc

WebDBC files always number the bits within a byte from the least significant to the most significant bit, and across bytes from the lowest addressed byte to the highest addressed byte. This means that for “Little Endian” messages, the low order bit of the 64-bit CAN messages is bit 0 and the bits are numbered in order of ascending order to bit 63.
