ISArcEx - A FreeArc Archive Extractor Plugin for InnoSetup

[BLACKFIRE69]

ISArcEx v0.5 — Update 02 (LibOnly)

* Bug fixes only. No API changes.

 - Fixed: `ISArcExReduceCalcAccuracy` did not perform as expected in v0.5
   due to an internal architectural change introduced in this version.
   This has been corrected and the function now behaves as intended again.

 - Fixed: `ISArcExCallbackInterval` silently ignored some values,
   causing progress updates to appear sluggish or unresponsive regardless
   of the configured interval. The valid input range has been restored.

 - Fixed: State inconsistency where accuracy reduction settings could
   behave unpredictably across multiple init calls in the same session.

* Notes:

 - Drop-in library replacement. No script-side changes required.
