Refactor Anonymous Functions to Utility Helpers in Tests

[adcondev]

This change refactors anonymous functions used for generating test data in pkg/commands/printposition/print_position_test.go and pkg/commands/print/print_test.go.

New utility helpers GenerateSequence and AppendByte were added to internal/testutils/byte_helpers.go to facilitate this refactoring. These helpers improve test readability and allow for code reuse across different test packages.

The changes were verified by running go test -v -race on the affected packages.
