TOF: fix retrieval of integer output buffer CompressorTask.cxx (#6194)

preghenella · web-flow · commit f94d7fb99267 · 2021-05-20T14:16:55.000+02:00
To fix retrieval of integer output buffer size output buffer size will be the sum of the command-line-specified buffer size and the value automatically calculated.
Unless a negative value is used as the command-line-specified buffer size, in which case a fixed buffer size is used.
