Bug 20889 – Support construction of std.bigint.BigInt from a sign and a byte-array magnitude

Support construction of std.bigint.BigInt from a sign and a byte-array magnitude. Having it in the library would avoid the necessity of workarounds seen in the wild like https://github.com/shove70/crypto/blob/4052a5ef41c604b274ffff8bf6011180cd3a474d/src/crypto/bigint.d#L91-L112 See related https://issues.dlang.org/show_bug.cgi?id=13804
