wrap: disable signale for std out with alternative method to signale.disable

[benjaminlim00]

Current

Using wrap with the --output-file option allows output to std out
example: open-attestation wrap ./examples/sample-certs.opencerts --output-file ./path/to/file

However this is done by disabling all outputs to std out using signale.disable()

Expected

We want to use an alternative method to disable all outputs by signale using an alternative method, except for error messages. We still want to see outputs from signale.error
