Removed decoding step and activate decoding by client

[L1m3D4rkn3ss]

FIX

There was an issue when decoding the docker logs with the json package on @bibs2091 's machine. Removing the two-step decoding and adding the decode argument to the client.build() call seems to fix the issue.

Additional context

@bibs2091 please add screenshots and error logs as well as your hardware, OS and software versions for everything.

[bibs2091]

environment:

• OS: macOS Monterey 12.4
• Chip: apple M1
• python: 3.9.12
• docker: 20.10.17
• docker api: 1.41
• docker desktop: 4.10.0
• i2-client: 0.4.0 (installed in conda environment)

Error Message

Tried i2 on the mirror image:

Tracing the error put me in this part of code:

I printed output before the json line and it gave this:
b'{"stream":"Step 1/2 : FROM alpineintuition/archipel-base-gpu"}\r\n{"stream":"\\n"}\r\n'

[bibs2091]

I had windows as an os and the i2 didn't work for me in the first place (refer to this https://github.com/alpineintuition/i2-cli/issues/30). So if it works on Linux and macOS is good enough!!

This will not work because we need the output to determine the number of steps.

Case like this (b'{"stream":"\\n"}\r\n') happend lot of times during the build, just ignore with something like:

output = json.loads(output.decode().split("\n")[0])

Maybe add this to the other place where we decode the docker output if it happend at all step.

I think the pattern is not regular, sometimes there is a lot of /n before the content we want. but I will try ur solution nevertheless
