Support boolean/char/string in createArray/arrayToJvm

[subes]

As discussed here: https://github.com/cnuernber/libjulia-clj/issues/4#issuecomment-1007677823

I guess when implementing string support, char support might come as a by-product, since the string already has to handle unicode encoding/decoding. Or if you go for byte[] transfer, then a char could be converted into a byte[2] for transport with the same logic I guess.

Though not a high priority issue.

Boolean also does not work with the tensor pathway: https://github.com/cnuernber/dtype-next/issues/52#issuecomment-1015736984
