[Tiny issue] api.rb shows a harmless "mismatched indentation" warning

[rubyFeedback]

Hello boazsegev,

Not sure if such small warnings should be filed as an issue, sorry. :)

But the good thing is that these are easy to correct.

Warning is this for me:

 /usr/lib/ruby/gems/2.7.0/gems/combine_pdf-1.0.18/lib/combine_pdf/api.rb:31: warning: mismatched indentations at 'rescue' with 'begin' at 25

I think the indent just has to be shuffled a bit to the right, for that warning
to disappear. (I think a single begin/rescue clause may suffice by the way;
nested begin/rescues are a bit harder to read, but that is aside from this
issue request - this one is solely about the warning. I noticed it because
I tend to run my .rb files with -w flag all the time).
