[Feature Request] Support other kinds of flame graphs

[QuarticCat]

For example, memory flame graph. https://www.brendangregg.com/FlameGraphs/memoryflamegraphs.html

This utility just provides some glue between running perf for you (on Linux, and other tools on other platforms) and the inferno crate for building the SVG. I don't know to which extent these dependencies would need changes in order to support this, but unfortunately I won't have time to work on this myself.

Using the existing command line options of this utility, it looks to support some of those out of the box to an extent (for ones that use 'perf').

Memory (brk() syscall):
cargo-flamegraph flamegraph --cmd "record -e syscalls:sys_enter_brk -a -g" -b

Memory (malloc calls):
perf probe --exec=/lib/aarch64-linux-gnu/libc.so.6 --add malloc
cargo-flamegraph flamegraph --cmd "record -e probe_libc:malloc -a -g" -b

Off-CPU (Block Device I/O):
cargo-flamegraph flamegraph --cmd "record -e block:block_rq_insert -a -g" -b
