LCD Digits

Your task is to create an LCD string representation of an integer value using a 3x3 grid of space, underscore, and pipe characters for each digit. Each digit is shown below (using a dot instead of a space)

._.   ...   ._.   ._.   ...   ._.   ._.   ._.   ._.   ._.
|.|   ..|   ._|   ._|   |_|   |_.   |_.   ..|   |_|   |_|
