Document Change to 2063-Z80 Board to Better fit Daughter Cards

[dennowiggle]

The purpose of this issue is to document a suggestion by John on Discord to allow better fit of daughter cards such as 2068-Z80-TMS9118 and 2065-Z80-programmer.

Currently through hole caps on 2063-Z80 are blocking daughter cards from using the standoff hole in the front right location on daughter cards.

How to address this issue:

• Remove the following capacitors and place surface mount replacements on the bottom side of the 2063-Z80 board.
• This solution has been tested with 0603 and 0805 capacitors on the bottom side of the board. These surface mount capacitors fit nicely across the through hole pads.
• Locations are : - 0.1uF C2, C4, C8 - 0.47uF C1, C11, C12

It would be nice if the Schematic and README files could document this change.
