Pull request overview
This PR migrates the TPPDF library to Swift 6 with strict concurrency checking enabled by updating the Swift tools version from 5.9 to 6.1 and adding necessary Sendable conformances throughout the codebase.
Key changes:
- Updated Swift tools version from 5.9 to 6.1 in Package.swift
- Added Sendable conformance to various public types (structs, enums, and classes)
- Changed static variables to static constants in test files for thread safety
- Marked test helper static variable as
nonisolated(unsafe)where needed
