custom typedoc theme

[janmazak]

In _typedoc, we had a custom theme that worked with an older version of typedoc, but is not compatible with v0.22 anymore.
The point of the theme was a better display format for union types.

The mechanism for custom themes is now completely different:

Our custom modifications of the default theme were like this:

diff -r default/partials/type.hbs ../../custom-theme/partials/type.hbs
65c65
<         {{> type needsParens=true}}
---
>         {{> type}}

>         <span style="display: block; text-indent: 15px">

<             {{#unless @first}}
<                 <span class="tsd-signature-symbol">; </span>
<             {{/unless}}
---
>         <span style="display: block; text-indent: 30px">

<         <span class="tsd-signature-symbol"> }</span>

<     {{#if needsParens}}
<         <span class="tsd-signature-symbol">(</span>
<     {{/if}}

Not worth it in terms of time and money.
