Fix dxDrawCircle segments argument

[ApeLsiN4eG]

Fixed a bug when it drew number of segments-1 segments instead of number of segments that you pass in the segments argument of the dxDrawCircle function.

For example:
dxDrawCircle(500, 500, 100, 0, 360, tocolor(255,255,255,255), tocolor(255,255,255,255), 4) draws a triangle with 3 segments instead of a square.
dxDrawCircle(500, 500, 100, 0, 360, tocolor(255,255,255,255), tocolor(255,255,255,255), 3) draws nothing.

Nice one!
Thank you for the PR and congratulations on your first contribution! =)

Small sidenote: in the future when you make a patch, I suggest you create a new branch such as bugfix/wrong-segment-count-in-dxDrawCircle and create a pull request from there instead of directly from your master branch, as this way you can keep different bugfixes and features separated from each other and makes the whole process troubleless for both sides. Your master branch should basically always be identical to our master branch.
