Hang and then timeout on certain files about exiftool-vendored.js

[mceachen]

v26.0.0 is released with this new option: https://photostructure.github.io/exiftool-vendored.js/interfaces/ExifToolOptions.html#ignoreMinorErrors

const { ExifTool } = require("exiftool-vendored")
new ExifTool({ ignoreMinorErrors: false }).read('evil.jpg').then(console.dir)

but the exiftool command line tool will not hang.

I suspect you're not running exiftool with all of the options that this library uses:

time exiftool -json -struct -all -ignoreMinorErrors test/issue-181.jpg > out.json

real	0m24.980s
user	0m24.350s
sys	0m0.617s

And out.json is a 33 megabyte file. The photoshop:DocumentAncestors field has 792,787 items.

So: obviously, at least for that file, you don't want to -ignoreMinorErrors! ExifTool only parses the first 1000 items by default, but refuses to parse some files without that argument.

The next release will support disabling -ignoreMinorErrors via ExifToolOptions.

Thanks so much @mceachen for the fast turn around on this!
