Method EncodePackedUInt64

encoder.go:198–211

EncodePackedUInt64 writes a list of 64-bit unsigned integers to the buffer using packed encoding, preceded by the varint-encoded tag key. This operation is O(n^2) because we have to traverse the list of values to calculate the total encoded size and write that size *before* the actual encoded value

(tag int, vs []uint64)
