Returns a compressor input stream from f, autodetecting the compressor type
from the first few bytes of f. Returns java.io.BufferedInputStream if the
compressor type is not known. Should be used inside with-open to ensure the
InputStream is properly closed.

Returns a compressor output stream from `f` and a compressor type `k`. `k`
must be selected from `:bgzip`, `:gzip` or `:bzip2`. Autodetects the
compressor type from the extension of `f` if `k` is not passed. Returns
`java.io.BufferedOutputStream` if the compressor type is not known. Should be
used inside with-open to ensure the OutputStream is properly closed.

Returns a created temporary directory with the given `prefix`.

Takes the temporary directory created by `create-temp-dir` and deletes the
`dir` and the files in `dir`.

Returns true if c is a visible character, false if not.

Returns true if c is a character that creates "white space" in displayed
text.

Casts to byte avoiding an error about out of range for byte.

bindings => [dir prefix ...]
Creates a temporary directory with the given `prefix` and binds the given
