Convert TCR to AZW3

The TCR file extension stands for Text Compressed for Readability, originally used by Psion Series 3 palmtop devices in the early 1990s. It stores eBooks in a proprietary format that offers better compression than PalmDOC, making it suitable for the limited storage of handheld devices. Despite the discontinuation of Psion devices, TCR files can still be read using modern eReaders like Sumatra PDF.

The AZW3 file extension, also known as Kindle Format 8 (KF8), is a proprietary eBook format developed by Amazon. Introduced in 2011 alongside the Kindle Fire, AZW3 supports advanced formatting features such as HTML5 and CSS3, enhancing the visual presentation of eBooks. It is primarily used for Amazon Kindle devices and applications, providing a richer reading experience compared to its predecessor, AZW. The format is backward-compatible with MOBI, ensuring older Kindle devices can still access the content.
