`bloaty -d compileunits` gives `bloaty: Don't know how to parse DWARF form: 21`

[James Lingard]

$ bloaty -d compileunits mylib.so --debug-file mylib.so.debug 
bloaty: Don't know how to parse DWARF form: 21

It works fine with -d symbols, or with no -d option.

I can try to provide a simple library that reproduces this, but to do so it would be helpful if you could tell me anything about what "DWARF form 21" is.

Looks like that would be DW_FORM_ref_udata:

Try #197 and let me know if it works for you.

That seems to fix it. Thanks!
