I know it wasn't the core part of the question, but note that BitConverter
isn't especially helpful for protobuf, unless you happen to be dealing with
[s]fixed{32|64} / float / double (it is unclear whether you mean "uint64" as
a protobuf type or a language-specific type).
Treating it as fixed/unsigned I get: 1453014483955211943
Treat it as a variant, though, and you get:
(handle continue bits)
0100100 1111001 0001001 0100101 1011110 0100111
(normalize)
01 00100111 10010001 00101001 01101111 00100111
= 1269450764071
