v3.0 - Update schema for inline code

[d0c-s4vage]

Describe the Feature Request
Inline code should be able to be customizable with:

• left/right padding - number of spaces to add to the left/right of the inline code
• highlighting style - use this pygments style to highlight the inline code
• code language used - assume all inline code is this language

Tips

This will involve:

• Creating a new schema in lookatme/schemas.py to hold the inline code settings (maybe nested inside a general "code" schema? then it'd be "styles.code.inline.<inline_style>"
• Adding the new top-level schema to the main StyleSchema

Maybe something like this:

class InlineCodeSchema(Schema):
    ...

class CodeSchema(Schema):
    inline = fields.Nested(InlineCodeSchema, ...)

class StyleSchema(Schema):
    ...
    code = fields.Nested(CodeSchema, ...)
    ...
