private byte[] getStringBytes() {
		return stringLayout.isPascal() ? getPascalCharBytes() : getNormalStringCharBytes();
	}
Returns the string contained in the specified {@link MemBuffer}, or null if all the bytes of
the string could not be read.
<p>
This method deals in characters of size {@link #charSize}, that might be
{@link #paddedCharSize padded} to a larger size. The raw n-byte characters are converted into
a Java String using a Java {@link Charset} or by using a custom Ghidra conversion. (see
convertBytesToStringCustomCharset)
<p>
The MemBuffer's endian'ness is used to determine which end of the {@link #paddedCharSize
padded } field contains our {@link #charSize} character bytes which will be used to create
the java String.

@return String containing the characters in buf or null if unable to read all {@code length}
        bytes from the membuffer.
