Change in xdo_search_t structure

[amasmiller]

When using python-libxdo v0.1.2a1 against libxdo version 3.20210903.1, I found the xdo_search_windows function was not working as expected.

I traced down the issue to a changed xdo_search_t structure made in this recent change to libxdo.

After the modification, the search worked as expected.
