Analytics.kt class warnings

[TomerPacific]

Building the project, I noticed the following warnings for the Analytics.kt class:

1. In the method generateOSVersionString:

private fun generateOSVersionString(major: Any, minor: Any? = "0", patch: Any? = null): String {
    val patchStr = if (patch != null) patch.toString().toAnalyticsVersionStr() else ""
    val minorStr = minor.toString().padStart(2, '0').toLong().toString(2).toAnalyticsVersionStr()
    val majorStr = major.toString().padStart(2, '0').toLong().toString(2).toAnalyticsVersionStr()

    return "$majorStr$minorStr"
}

patchStr is never used

2. In the method String.toAnalyticsVersionStr()

private fun String.toAnalyticsVersionStr(): String {
    val num = this.toInt(2)
    return when (val num = this.toInt(2)) {
        in 0..25 -> {
            ('A' + num).toString()
        }
        in 26..51 -> {
            ('a' + num - 26).toString()
        }
        else -> ('0' + num - 52).toString()
    }
}

the local variable num is never used

3. In the method String.toAnalyticsVersionStr()

private fun String.toAnalyticsVersionStr(): String {
    val num = this.toInt(2)
    return when (val num = this.toInt(2)) {
        in 0..25 -> {
            ('A' + num).toString()
        }
        in 26..51 -> {
            ('a' + num - 26).toString()
        }
        else -> ('0' + num - 52).toString()
    }
}

There are two variables named num, thus causing variable shadowing

Relates to #107

I'd like to fix this, if possible.
