MAMS 3.0.0 (2024-09-30)

• Added 2 new designs: method = 'separate' for MAMS with a separate stopping rule method = 'dtl' for drop-the-losers design where method = 'simultaneous' (default) corresponds to the MAMS with a simultaneous stopping rule
• refined the summary(), print() and plot() functions for "MAMS" objects accordingly
• updated the C code to compile with STRICT_R_HEADERS=1 (mandatory for R >= 4.5.0) ——————--CHANGE LOG——————————————--
