Version number

If protozero/version.hpp is included, the following macros are set:

Macro	Example	Description
`PROTOZERO_VERSION_MAJOR`	1	Major version number
`PROTOZERO_VERSION_MINOR`	3	Minor version number
`PROTOZERO_VERSION_PATCH`	2	Patch number
`PROTOZERO_VERSION_CODE`	10302	Version (major * 10,000 + minor * 100 + patch)
`PROTOZERO_VERSION_STRING`	"1.3.2"	Version string

Changing Protozero behaviour

The behaviour of Protozero can be changed by defining the following macros. They have to be set before including any of the Protozero headers.

`PROTOZERO_STRICT_API`

If this is set, you will get some extra warnings or errors during compilation if you are using an old (deprecated) interface to Protozero. Enable this if you want to make sure your code will work with future versions of Protozero.

`PROTOZERO_USE_VIEW`

If this is unset protozero::data_view is Protozero's own implementation of a string view class.

Set this if you want to use a different implementation such as the C++17 std::string_view class. In this case protozero::data_view will simply be an alias to the class you specify.

#define PROTOZERO_USE_VIEW std::string_view

This affects the result type of the pbf_reader::get_view() method and a few others taking a protozero::data_view as parameters.
