Remove unused methods from PhysicalHoldingsMarkupBuilder

[hackartisan]

These don't look like they're used anywhere.

orangelight/app/services/physical_holdings_markup_builder.rb

Lines 322 to 353 in e401c9f

	def self.scsb_supervised_request_link
	link_to('Reading Room Request',
	"/requests/#{doc_id}?source=pulsearch",
	title: 'Request to view in Reading Room',
	class: 'request btn btn-xs btn-primary',
	data: { toggle: 'tooltip' })
	end
	def self.scsb_request_link
	link_to(request_label(location_rules),
	"/requests/#{doc_id}?source=pulsearch",
	title: request_tooltip(location_rules),
	class: 'request btn btn-xs btn-primary',
	data: { toggle: 'tooltip' })
	end
	def self.ils_request_link
	link_to(request_label(location_rules),
	"/requests/#{doc_id}?mfhd=#{holding_id}&source=pulsearch",
	title: request_tooltip(location_rules),
	class: 'request btn btn-xs btn-primary',
	data: { toggle: 'tooltip' })
	end
	def self.request_link
	link_to('Reading Room Request',
	"/requests/#{doc_id}?mfhd=#{holding_id}&source=pulsearch",
	title: 'Request to view in Reading Room',
	class: 'request btn btn-xs btn-primary',
	data: { toggle: 'tooltip' })
	end

And half of them would error if they were used because they wouldn't know what location_rules meant, because it's not passed into those methods.
