Support Zig 0.14 (#11)

#### Problem

Zig 0.14 is out, but the library is still on 0.13.

#### Summary of changes

Mostly straightforward changes:

* Update the library name to solana_program_sdk
* Bump to a new minor version
* Update documentation
* Use the new `addWriteFiles` API for the linker script
* Use the new `Alignment` API for allocators and fix the tests
* Update Rust deps for program-test to v2.2
* Update CI

 need to install base58 and clap:
