AppleDict-bin: fix crash for multidirectional dicts

[soshial]

DCSPrivateFlag may be bigger than 0x20. Fixed that.

DCSDictionaryLanguages array inside plist file has a list of dictionaries inside this file
This DCSPrivateFlag per each article provides not only priority and parental control, but also a flag of translation direction:

• 0x0-0x1f values are reserved for the first language from the DCSDictionaryLanguages array
• 0x20-0x3f values are reserved for the second language etc.

Use f-string.

Can we move all this if-elses to a method of properties that return priority and parentalControl?

[soshial]

Well, in readKeyTextData() we list through a single file and extract one value straight after another. If it's all in one method, we can see the exact order. If the logic is in several methods, then those methods might change order by mistake...

extractLexeme()
extractFlags()
extractForms()

I don't know.
