* Add support for reading iTXt chunks

* Add support for writing iTXt chunks

* Remove Test Decode_TextEncodingSetToUnicode_TextIsReadWithCorrectEncoding: Assertion is wrong, the correct keyword name is "Software"

* Add support for writing zTXt chunk

* Add an encoder Option to enable compression when the string is larger than a given threshold

* Moved uncompressing text into separate method

* Remove textEncoding option from png decoder options: the encoding is determined by the specification: https://www.w3.org/TR/PNG/#11zTXt

* Removed invalid compressed zTXt chunk from test image

* Revert accidentally committed changes to Sandbox Program.cs

* Review adjustments

* Using 1024 bytes as a limit when to compress text as recommended by the spec

* Fix inconsistent line endings

* Trim leading and trailing whitespace on png keywords

* Move some metadata related tests into GifMetaDataTests.cs

* Add test case for gif with large text
