Update compile version and fix cast map

[Daevsoft]

This PR fixes a Kotlin return type mismatch that occurs when building with Kotlin 1.8+ or 1.9+.
The previous implementation returned a HashMap<String, Any?> while the declared return type was HashMap<Any, Any>, which causes a build failure due to stricter generic variance checks introduced in newer Kotlin versions.

Return type mismatch: expected 'java.util.HashMap<kotlin.Any, kotlin.Any>',
actual 'kotlin.collections.HashMap<kotlin.String, it(kotlin.Comparable<*>? & java.io.Serializable?)>'

🧩 Root Cause

Kotlin 1.8 and above enforces stronger generic type safety.
Returning HashMap<String, Any?> when the function signature expects HashMap<Any, Any> is no longer allowed implicitly.

🔧 Changes Made

Updated the function in LocationParserUtil.kt to use consistent generic types between declaration and return value.
Example fix:

fun toMap(location: Location): HashMap<String, Any?> {
    val map = HashMap<String, Any?>()
    ...
    return map
}

(Alternatively, the fix may safely cast the map to HashMap if necessary.)

✅ Result
Plugin now compiles successfully with:

• Kotlin 1.8.x and 1.9.x
• Android Gradle Plugin 8.x
• compileSdkVersion 34

No behavioral changes to runtime logic.

🔬 Tested On

• Flutter 3.24.3
• Kotlin 1.9.24
• Android Gradle Plugin 8.6.0
• Android SDK 34

#🧠 Notes

This change maintains backward compatibility with older Kotlin versions while ensuring successful builds for projects using modern Flutter/Android toolchains.
