Fix error on parsing a floating point value which ends with a dot

fktn-k commented 1 month ago

As reported in the issue #380, the current parser emits an error on parsing a floating point value which ends with a dot.
That is because, while scanning a parsed scalar, the parser mistakenly assumes decimals after a dot.
However, the spec explicitly allows omitting decimals after a dot here as the regular expression for the float tag.

So, this PR has fixed implementation to follow the spec, and the updated parser now correctly parse such floating point values.
To validate the changes, some relevant test cases have also been added to the test suite.

Please don't

The C++11 support varies between different compilers and versions. Please note the list of supported compilers. Some compilers like GCC 4.7 (and earlier), Clang 3.3 (and earlier), or Microsoft Visual Studio 13.0 and earlier are known not to work due to missing or incomplete C++11 support. Please refrain from proposing changes that work around these compiler's limitations with #ifdefs or other means.
Please refrain from proposing changes that would break YAML specifications. If you propose a conformant extension of YAML to be supported by the library, please motivate this extension.
Please do not open pull requests that address multiple issues.
