Dependency bumps

[garethsb]

In order to spot incompatibilities early, we have generally tried to keep the OSS master branch close to latest versions of build dependencies.

Right now, there are quite a few things we could try bumping...

In nmos-cpp GitHub Actions workflow

• lukka/get-cmake v3.24.2
• lukka/run-cmake v10 (if we want to adopt cmake presets...)
• actions/setup-python v4 (v4.3.0)

In Development/conanfile.txt

• openssl 1.1.1s
• boost 1.80.0

In Development/cmake/NmosCppConan.cmake

• CONAN_VERSION_MIN 1.50.0
• CONAN_VERSION_CUR 1.53.0

In Development/cmake/NmosCppDependencies.cmake

• BOOST_VERSION_CUR 1.80.0

In Development/third_party/nlohmann

• json.hpp 3.11.2

In Documents/Dependencies.md

• cmake 3.24.2
• conan 1.53.0
• boost 1.80.0 (quite a few places)
• openssl 1.1.1s

I suggest we leave Catch as the really old v1.10.0 for now since that's just a test dependency.

I suggest we remove Sandbox/conanfile.py.

In nmos-cpp recipe on Conan Center

• required_conan_version >=1.47 or >=1.50 (maybe??)
• openssl 1.1.1s
• boost 1.80.0
• cmake 3.24.2

But before updating that recipe we need...

In json-schema-validator on Conan Center:

• nlohmann_json 3.11.2

In websocketpp recipe:

• boost 1.80.0
• openssl 1.1.1s
• zlib 1.2.13
• (standalone) asio 1.24.0 (maybe??)

In cpprestsdk recipe:

• boost 1.80.0
• openssl 1.1.1s
• zlib 1.2.13

@lo-simon I created PRs for:

• json-schema-validator - [json-schema-validator] Conan v2 support conan-io/conan-center-index#13959
• websocketpp - [websocketpp] Conan v2 support conan-io/conan-center-index#13961
• cpprestsdk - [cpprestsdk] Conan v2 support conan-io/conan-center-index#13962

but they're all failing the Conan 2.0 migration linter checks, so need some help with that...

All mentioned version ups were included in #291 apart from lukka/run-cmake which is tracked in #284.

Conan recipes for json-schema-validator, websocketpp, and cpprestsdk (after a couple of follow-up conan-center-index PRs and #297, #299 to work around resulting issues with these and the recently changed avahi recipe) are now migrated to v2. I've got a PR in progress for the conan-center-index nmos-cpp recipe, currently based off tip of master, so cci.20221116.
