Is your feature request related to a problem? Please describe.

Since the project doesn't have a mechanism for preventing memory leaks, there are high chances to introduce memory leaks during the development.

Describe the solution you'd like

• Make use of a safe pointer (smart pointer) or scoped deleter for 3rdparty library/internal memory allocation.
• Run unit/integration tests with memory sanitizer/tracker (e.g., valgrind/asan)

Additional context

There are many cases that we introduced memory leak problems.

• Fix memory leak in deflate decoder #37
• Fix a memory leak and update release notes for v0.19.0 #9
