[BUG] Escape Sequence is written wrong

[jgy90]

when string is \t or \n, if i convert unicode escape to character, it come out just t not \t

unicode-escaper/src/main/kotlin/com/materkey/codepoints/FromCodePointsConverter.kt

Lines 59 to 70 in 92b7a00

	if (hadSlash) {
	// handle an escaped value
	hadSlash = false
	when (ch) {
	'u' -> inUnicode = true
	else -> out.write(ch.toInt())
	}
	continue
	} else if (ch == '\\') {
	hadSlash = true
	continue
	}

if hadSlash is true but ch is not u, then \\ should write before ch

else -> out.write('\\' + ch.toInt()) 

Consider it please
