    gchecksum: Drop preconditions for checksum_type being valid
    
    Instead, return `NULL` if the checksum type is unsupported. This may
    come in useful if we have to withdraw support for a particular checksum
    type in future, due to it being broken.
    
    These semantics were already in place for the return value of
    `g_checksum_new()` — see commit 877cc60f and bug
    comment https://bugzilla.gnome.org/show_bug.cgi?id=501853#c6.
