Snapchat assigns sequential IDs that happen to overlap real epoch
values, so the 10-16 digit timestamp regex matched and produced
2002-era dates for files actually saved in 2016/2021. The digits
themselves are indistinguishable from a unix timestamp, so we
dispatch on the source-app prefix instead. Case-insensitive,
extensible for future apps that exhibit the same pattern.
