Fix the following vulnerability:
- CVE-2025-46728
cpp-httplib is a C++ header-only HTTP/HTTPS server and client library.
Prior to version 0.20.1, the library fails to enforce configured size
limits on incoming request bodies when `Transfer-Encoding: chunked` is
used or when no `Content-Length` header is provided. A remote attacker
can send a chunked request without the terminating zero-length chunk,
causing uncontrolled memory allocation on the server. This leads to
potential exhaustion of system memory and results in a server crash or
unresponsiveness. Version 0.20.1 fixes the issue by enforcing limits
during parsing. If the limit is exceeded at any point during reading,
the connection is terminated immediately. A short-term workaround
through a Reverse Proxy is available. If updating the library
immediately is not feasible, deploy a reverse proxy (e.g., Nginx,
HAProxy) in front of the `cpp-httplib` application. Configure the
proxy to enforce maximum request body size limits, thereby stopping
excessively large requests before they reach the vulnerable library
code.
