/** \brief Returns a vector of usable Compression Types
*
* Files can be compressed in various ways to decrease the size of the
* download. Therefore the Acquiremethods support a few compression types
* and some archives provide also a few different types. This option
* group exists to give the user the choice to prefer one type over the
* other (some compression types are very resource intensive - great if you
* have a limited download, bad if you have a really lowpowered hardware.)
*
* This method ensures that the defaults are set and checks at runtime
* if the type can be used. E.g. the current default is to prefer bzip2
* over lzma and gz - if the bzip2 binary is not available it has not much
* sense in downloading the bz2 file, therefore we will not return bz2 as
* a usable compression type. The availability is checked with the settings
* in the Dir::Bin group.
*
* \param Cached saves the result so we need to calculated it only once
* this parameter should ony be used for testing purposes.
*
* \return a vector of (all) Language Codes in the prefered usage order
