Provide default arguments for Asn1TreeBuilder.() -> Unit

[ShiinaSekiu]

In some practices we may not use the child node builder.

Asn1.ExplicitlyTagged(34U) { }

signum/indispensable/src/commonMain/kotlin/at/asitplus/signum/indispensable/asn1/encoding/Asn1Encoding.kt

Line 191 in e8f9bd4

fun ExplicitlyTagged(tag: ULong, root: Asn1TreeBuilder.() -> Unit): Asn1ExplicitlyTagged {

Maybe it should be changed to?

fun ExplicitlyTagged(tag: ULong, root: Asn1TreeBuilder.() -> Unit = { }): Asn1ExplicitlyTagged {

Personally, I think the intentions are clearer, if the empty lambda needs to be spelled out. After all you are creating an empty structure. Therefore, I think the code should clearly mirror this intent.
