Dukat 0.5.7 generates import statements that are illegal in Kotlin

[abrooksv]

Kotlin does not allow escaped identifiers to be used in imports making this code not work:

import MetadataBearer as $MetadataBearer

@Suppress("NESTED_CLASS_IN_EXTERNAL_INTERFACE")
external interface AccountLimitExceededException : __SmithyException, `$MetadataBearer` {
    override var name: String /* "AccountLimitExceededException" */
    override var `$fault`: String /* "client" */
    var message: String?
        get() = definedExternally
        set(value) = definedExternally

    companion object {
        var filterSensitiveLog: (obj: AccountLimitExceededException) -> Any
        var isa: (o: Any) -> Boolean
    }
}
