Adapter.replace, one-to-one only

[dhilt]

For issue #171.

We definitely need this. Replacement with "remove + insert" has an issue if we work with elements in the viewport.

@duxor Hi! At least 1-2 weeks are needed to complete the in-viewport many-to-many replacement feature. But one-to-one replacement is already done, and if you need it, I can release ngx-ui-scroll v1.11.0-rc

Hi @dhilt
It should be great, please do it, thanks.

@duxor ngx-ui-scroll v1.11.0-rc is on npm, it has basic Adapter.replace implementation. The syntax as follows:

datasource.adapter.replace({
  predicate: ({ $index, data, element }) => $index === indexToReplace,
  items: [itemToReplace]
})

Note, predicate must return true no more than 1 time, items must contain only 1 item. Would be great to get any feedback on this!

@dhilt awesome! Works as expected, thanks.
