Tweaks

[randomizedcoder]

@cosmo0920 Thanks for the work on fluent-bit-go

I made a little branch with a couple of other minor tweaks.

1. Dump go version, and update the dependency
   go 1.20
   github.com/ugorji/go/codec

2. Verify timestamp without reflection
   To verify the timestamp is being decoded correctly added a extractTimeStamp() function to extract the time without using reflection.

3. More test data
   Also tried to add another test input, and this actually fails. I believe the input data is valid, because I extracted it from my running version of fluentbit. Have I just made a coding error, or has it found a real issue? I added some log lines, and the input data looks ok-ish.

Don't bump the Go version until it's necessary.

Could you add your test data as binary arrays instead of adding binary files? Adding binary files leads to decrease maintainability for test cases.
