Initialize first field in named union constructors

[lethosor]

This allows job_spec_data fields embedded in other types to be initialized to -1 as expected

[lua]# ~df.manager_order:new().specdata
<job_spec_data: 0x7fffac2e267c>
hist_figure_id           = -1
race                     = -1
improvement              = -1

Full diff of codegen output - extra eyes on this appreciated, as I haven't verified that all of the changes are reasonable:

This looks good to me in general, but I notice that some of the fields are being initialized to -1 and I don't understand why this happens. Why is, for example, hist_figure_id being initialized to -1 in job_spec_data. While I agree that this is correct (or at least reasonable, I haven't checked to see what DF's own constructor does in this situation and is in fact what DF does), I don't understand what in either codegen or the XML is causing that to happen.

That's handled here in render_field_init: https://github.com/DFHack/df-structures/blob/833a1fd45905cd6c57be037ea940189cd19b339c/StructFields.pm#L423-L428
