Configurable + automatic indicator position relative to stack

[AdamWagner]

Configuration ideas:

Indicator position relative to stack:

1. Top/bottom
2. Left/right
3. Inside/outside

Indicator position offset relative to stack:

• top offset
• bottom offset
• left offset
• right offset

Values may be integers or percentages. Values may be negative.

Options may be repeated / combined to achieve @alin23's mockup here with indicators that are centered on the edge of window and occlude a small amount of the window content.

Automagic™ positioning

Automatically position indicators on the outside edge of the stack nearest the edge of the screen. This would be nice for users who use small or no window gaps and modest screen padding.

Examples for configuration variable names / values from @alin23

stack_dock_top_offset 0
stack_dock_top_offset 5%
stack_dock_top_offset 10%

Somewhat addressed by window offset config settings in: https://github.com/AdamWagner/stackline/pull/18/commits/c30e8556950b1dc39b21ea96009063edde475dcd#diff-8aa92ecfa197cc600dd2ac0ef22d3fb9R58

besides the default "smart" positioning, could we still get the option to force the position of the indicators to always be top, bottom, left or right please? Thanks
