* feat: add tr_strbuf class for building tmp strings
Based on fmt::basic_memory_buf, this is a growable string buffer that
has an initial size that's large enough to build most filenames or URLs
without needing heap allocations.
Adds a couple of extra helpers such as a `c_str()` method to make dealing
with old zero-terminated string APIs easier.
