This PR adds group filtering to the strace filter options. The groups available are {"desc", "file", "ipc", "network", "process", "signal", "memory", "stat", "lstat", "fstat", "stat_like", "statfs", "fstatfs", "statfs_like", "pure", "syscall_never_fails", "max_args", "memory_mapping_change", "stackcapture_on_enter", "compat_syscall_types", "seccomp_default", "creds", "clock", "comm_change"}.
The table specifying the syscall groups mimics the strace source, a combination of these two files - https://gitlab.com/strace/strace/-/blob/master/src/linux/x86_64/syscallent.h & https://gitlab.com/strace/strace/-/blob/master/src/sysent_shorthand_defs.h
