fail to install on PHP8

[elfeffe]

I just try to require as usual, but instead of php7.4, I'm trying with php8.

It fails because it requires macroable1.0, and macroable1.0 requires php7.

Our tests indicate that it is perfectly installable under PHP 7.4

Could you try to install it in a fresh project?
