@putout/plugin-split-variable-declarations

• The let statement declares a block-scoped local variable, optionally initializing it to a value.
• const statements are also block-scoped. The value of a constant can't be changed through reassignment, and it can't be redeclared. However, if a constant is an object or array its properties or items can be updated or removed.

🐊Putout plugin adds ability to find and split variable declarations because (re)moving a line is simpler and less error prone then changing coma (,) to colon (;). For the same reason, diff of changed declarations are more comfortable to read. Merged with @putout/plugin-variables.
