Error if URI exceeds 64 characters

I have a uri like this

uri = "unix:///Users/muzammil.shahbaz/.local/share/containers/podman/machine/podman-machine-default/podman.sock"
This exceeds the standard 64 characters.

On execution, I get the following error:

```
Exception has occurred: UnicodeError
encoding with 'idna' codec failed (UnicodeError: label empty or too long)

The above exception was the direct cause of the following exception:

File "../podmanclient.py", line 12, in
version = client.version()
```

A potential fix would be to encode the URL to base64 and handle decoding in the code.

I am using podman version 4.1.1 on OSX using qemu virtual machine.
