Skip More Than Available test case in chunked_buff.go is failing

[ackris]

The test case Skip More Than Available in chunked_buff_test.go of utils is failing because the Skip method is not correctly handling the situation where the requested skip size exceeds the available bytes in the buffer. Specifically, it seems that the method is returning the wrong number of bytes skipped.

{
    name:           "Skip More Than Available",
    input:          []byte("Hello"),
    readSize:       0,
    skipSize:       10,
    expectedOutput: []byte(""),
    expectedSkip:   5,
},
