Addresses #270
Partially addresses #341: both the fill and flatten operations work as intended. However, the PDF seems to be invalid the sense that the choice/combo field has an
Iarray with a single value present, which causes the first value in the selection list to always be shown when opening the file. According to the specifications, theIfield should be used only for fields that support multiple selection, which is not the case there. Setting that field to nil before the fill operation should solve the issue (the flatten operation works as intended using the PR, without removing theIvalue). See section 12.7.4.4 "Choice Fields" (pp. 444-446) of the PDF specs for more details.This change is
