Special equality check for time.Time

• Using time.Equal to compare two time.Times for equality
• Adjusted variable name in examples from tt to assert

Match and NotMatch asserters

• New asserters - Match and NotMatch - to test a string against a regular expression.
• Fail fast in Expect when checking for a nil error, in order to avoid excessive failures when asserting the return arguments of a function call

HTML asserters

• HTMLMatch and HTMLNotMatch enable searching inside the DOM of an HTML document
• Additional unit tests
• Attribution.MD file

Not/Contains: support mix of string and []byte

Cast to string when Contains or NotContains get a mix of string and []byte arguments.

Improved testing

Improved unit tests to check for both the application of a failure on t and the return value of the asserter.

Nil equality check, Expects

• Improved the Equal and NotEqual asserters to better detect nil values
• Added a new asserter Expect for an equality checks of a list of arguments

Improvements to Contains and NotContains

• Added explicit support for []byte containing or not containing a sub []byte
• Performance optimization for element matching in slices and maps

Fuller stack trace on fail

• Print the full stack trace with a failure message, not just a single stack frame

--- FAIL: Test_Something
    /github.com/microbus-io/testarossa/some_test.go:389
    /github.com/microbus-io/testarossa/some_test.go:154
    Expected 'foo' to contain 'bar'

Nil check

• Check for nil TextMarshaler and Stringer

Additional improvements to failure messages

• Improve detection of stack location
• Truncate large value strings to 1K in length
• Fix: missing type name in failure message when the type doesn't have a length
