HISTORY imsplice: Splicing the two readouts (A&B) per CCD into a unique image   
HISTORY imsplice: Splicing results in all detectors as if read from A amplifier 
HISTORY imsplice: NEXTEND keyword updated (/2) = number of CCDs vs. amplifiers  
HISTORY imsplice: EXTNAME keyword becomes `ccdxx` instead of `ampxx`            
HISTORY imsplice: AMPNAME keyword now covers both amplifiers (eg `29a + 29b')   
HISTORY imsplice: keyword {GAIN, RDNOISE, MAXLIN} replaced by two keywords [A,B]
HISTORY imsplice: DATASEC and DETSEC keywords now reflect the entire CCD        
HISTORY imsplice: BIASSEC becomes irrelevant -> replaced by BSECA & BSECB       
HISTORY imsplice: New keywords are DETSECA, DETSECB, DSECA, DSECB, TSECA, TSECB 
HISTORY imsplice: New keywords are ASECA, ASECB, CSECA, CSECB
