Generate icons with custom path

[SamBarFu]

Description

A functionality is added so that through the command line the path where the generated icons will be saved can be specified.

Problem or Related Task

While working on my project, which required the icons to be executed in a specific path, the opportunity arose for the icon save path to be managed from the command line.

Changes Made

The scope of the variable iconsPath is changed to let, as it is intended to be updated in case a new path comes from the command line.

Within the generateIcons function, a validation is added to determine if there is a string in the argIconNames array that starts with --path=. If this condition is true, the index where the match of the string starting with --path= is found is obtained. Then, the value of the path is obtained by substring starting from the length of --path=. Finally, the path is obtained, and the value of iconsPath is reassigned.

If it cannot be identified that a string starting with --path= exists in the array, the value of iconsPath remains with the default value.
