Provide 0-23 hour formatting

[vlsi]

The current %H results in 01-24 output which looks surprising for the horizontal axis:

What I want is to represent "time since the beginning", so I would expect 00 to be formatted as 00 rather than 24.
Unfortunately, 0->24 conversion is hardcoded in

lets-plot/base-portable/src/commonMain/kotlin/jetbrains/datalore/base/dateFormat/DateTimeFormat.kt

Lines 111 to 115 in def7c2d

	private fun getHours24(dateTime: DateTime): Int =
	when(dateTime.hours) {
	0 -> 24
	else -> dateTime.hours
	}

The data is

val data = mapOf(

    "time" to doubleArrayOf(0.0, 90*60*1000.0, 2*90*60*1000.0) ,

    "rate" to doubleArrayOf(0.0, 50.0, 250.0)

)

val plot = letsPlot(data) + geomLine { x = "time"; y = "rate" } +

        scaleXDateTime("Time", expand = listOf(0, 0), format = "%Hh %Mm")
