* Add support for generating perf maps for simple perf profiling * add missing enum entry in C code * bugfix: use hexa when printing the code region's length too (thanks bjorn3!) * sanitize file name + use bufwriter * introduce --profile CLI flag for wasmtime * Update doc and doc comments for new --profile option * remove redundant FromStr import * Apply review feedback: make_line receives a Write impl, report errors * fix tests? * better docs
