tag is written. The value is a hash reference. The hash keys
are the names of the tags to write, and the values are
evaluated to obtain the ValueConv values of each tag (or undef

- parent tag (which may be undef if the tag is being deleted,

- WriteAlso tags), and the %opts hash may be accessed to modify
- SetNewValue options for each tag. By default, Type is set to
- "ValueConv" and the Protected option has bit 0x02 set to allow
- writing of Protected tags that aren't directly writable. The
- AddValue, DelValue, Shift and Replace options from the parent
