[Bug]: Consuming raw bytes with CLI return incorrect data

[nacardin]

Steps to reproduce:

1. Create a file test.bin with the following bytes 0x48, 0x65, 0x6C, 0x6C, 0x6F, 0x20, 0xF0, 0x90, 0x80, 0x57, 0x6F, 0x72, 0x6C, 0x64. This is from https://doc.rust-lang.org/std/string/struct.String.html#method.from_utf8_lossy "Incorrect bytes" example

$ fluvio produce bin-test --raw -f test.bin
$ fluvio consume -B bin-test -O raw > test-output.bin

In the test-output.bin file, the bytes will be 0x48, 0x65, 0x6C, 0x6C, 0x6F, 0x20, 0xEF, 0xBF, 0xBD, 0x57, 0x6F, 0x72, 0x6C, 0x64, 0x0A. 0xF0, 0x90, 0x80 is replaced by 0xEF, 0xBF, 0xBD.

I believe this happens to the inappropriate use of from_utf8_lossy in

fluvio/crates/fluvio-cli/src/client/consume/record_format.rs

Line 77 in 29d1a11

String::from_utf8_lossy(record).to_string()

This is binary data, it should not be parsed as utf8.
